■Temperature and Reliability
Fastening Torque
The reliability of an IC is highly dependent on its operating temperature. Design should pay particular attention to ensuring ample space
for radiating heat.
Be sure to apply silicon grease to the IC before attaching a heatsink,
and to secure it firmly to the heatsink.
Other important items to be considered regarding heat radiation include air convection during operation.

PD is given by the following formula:
PD=IO•[VIN(mean)–VO]

■Setting DC Input Voltage
• Shin-Etsu Chemical Co., Ltd.: G746
• GE Toshiba Silicone Co., Ltd.: YG-6260
• Dow Corning Toray Silicone Co., Ltd.: SC102
Please be careful when selecting silicone grease since the oil in some
grease may penetrate the product, which will result in an extremely
short product life.
■Calculating Internal Power Dissipation (PD)
The waveform of a DC input voltage is shown below.
VIN (max.)
VIN (mean)
VIN (min.)
Input Ripple
When setting the DC input voltage, pay attention to the following:
●VIN(min) must be no less than the sum of output voltage and dropout
voltage.
●VIN(max) must be no more than the maximum rated DC input voltage.
■Heatsink Design
The maximum junction temperature Tj(max) given in the absolute maximum ratings is specific to each product type and must be strictly
observed. Thus, thermal design must consider the conditions of use
which affect the maximum power dissipation PD(max) and the maximum ambient temperature Ta(max).
To simplify thermal design, the relationship between these two parameters has been presented in a graph, the Ta-PD characteristic
graph. Thermal design should include these steps:
1. Obtain the maximum ambient temperature Ta(max).
2. Obtain the maximum power dissipation PD(max).
3. Look for the intersection point on the Ta-PD characteristic graph
and determine the size of the heatsink.
The size of the heatsink has now been obtained. However, in actual
applications, a 10 to 20% derating factor is introduced. Moreover, the
heat dissipation capacity of a heatsink highly depends on how it is
mounted. Thus, it is recommended to measure the heatsink and case
temperature in the actual operating environment.
The Ta-PD characteristics for each product type are provided for reference purposes.
■Recommended Silicone Grease
■Others
• Devices can not be operated in parallel to increase current.
• An isolation type diode is provided from input to ground and also
from output to ground. These may be destroyed if the device is reverse biased. In this case, use a diode with low VF to protect them.
■Rectifier Diodes for Power Supplies
To rectify the AC input using rectifier diodes in power supplies, use
any of the SANKEN rectifier diodes shown in the following list. (Use
axial type diodes in a center-tap or bridge configuration.)

The output voltage may be increased by inserting resistor REX between
terminals No.4 (sensing terminal) and No.3 (output terminal). The current IREX flowing into terminal No.4 is 1mA (typ.), therefore the adjusted
output voltage VOUT is:
VO=V04+IREX•REX *V04: output voltage of SI-3000F series
However, the internal resistor (between terminals No. 4 and No.1) is a
semiconductor resistor, which has approximately thermal characteristics of +0.2%/°C.
It is important to keep the thermal characteristics in mind when adjusting the output voltage.

The output voltage may be increased by inserting resistors REX1 between terminals No.4 (sensing terminal) and No.3 (output terminal) and
REX2 between terminals No.4 and No.1 (ground terminal).
The current I4IN flowing into terminal No.4 is 1mA (typ.) so the thermal
characteristics may be improved compared to the method shown in 1
by setting the external current IREX1 at approximately 5 times the value
of I4IN (stability coefficient S=5).
The adjusted output voltage VOUT in this case is:
VO=V04+REX1•IREX1
IREX1=S•I4IN

output current may not be obtained due to the S.O.A. protection
circuit in the SI-3000F series.

: Output capacitor (Approx. 200µF)
: Oscillation prevention capacitor (C1: Approx. 47µF)
The distance between terminals No.5 (VIN) and No.1 (GND)
must be made as short as possible. If the input line is inductive or in the case of long wiring, a capacitor of approximately 0.33µF with superior high frequency characteristics
must be connected in parallel. Tantalum capacitors are recommended for C1 and C0, particularly at low temperatures.
: Delay capacitor (reset output)
: Pull-up resistor (300Ω or above)
: Protection diodes
These diodes are required for protection against reverse
biasing of the input and output. Sanken EU2Z is recommended.

The reliability of peripheral components such as capacitors and coils
is closely related to temperature. A high operating temperature may
reduce the service life. Exceeding the allowable temperature may burn
the coils or damage capacitors. It is important to make sure that the
temperature of output smoothing coils and input/output capacitors do
not exceed their allowable levels during operation. Allow for variation
in the ratings of the coils and minimize heat emission as far as possible. (For peripheral components, refer to the user manuals.)

■Example of Printed Circuit Board

a) For optimum operation, there must be only
one GND line originating from terminal 4
and each component must be connected
with the shortest possible wiring.
b) To prevent heating of the IC, it is best to
make the GND pattern as large as possible since the internal frame and terminal 4 (GND) are connected to each other.

Thermal design for D1 must be considered separately.
■Selecting External Components
1. Inductor L1
1) It must be suited for switching regulators.
Do not use inductors such as noise filters, because they generate excessive heat.
2) It must have the appropriate inductance value.
If the inductance is too small (150µH or lower), abnormal oscillation may occur causing operation problems in the overcurrent protection
circuit within the rated current range.
3) The rated current must be satisfied.
If the rated current is exceeded, magnetic saturation leads to overcurrent.
2. Capacitors C1 and C2
1) They must satisfy the breakdown voltage and allowable ripple current.
Exceeding the ratings of these capacitors or using them without derating shortens their service lives and may also cause abnormal
oscillation of the IC.
2) C2 should be a low-impedance type capacitor.
A low-impedance type capacitor is recommended for C2 to ensure reduced ripple voltage and stable switching operation.
3. Diode D1
The Sanken SFPB54 diode is recommended for D1. If you intended to use an equivalent diode, be sure to use a Schottky Barrier diode and
make sure that the reverse voltage applied to terminal 2 of the IC does not exceed the value (–1V) given in the absolute maximum ratings. If
you use a fast recovery diode or any other diode, supplying a reverse voltage generated from the recovery or ON voltage of the diode may
damage the IC.

1. Inductor L1
1) It must be suited for switching regulators.
Do not use inductors such as noise filters, because they generate excessive heat.
2) It must have the appropriate inductance value.
If the inductance is too small (150µH or lower), abnormal oscillation may occur causing operation problems in the overcurrent protection
circuit within the rated current range.
3) The rated current must be satisfied.
If the rated current is exceeded, magnetic saturation leads to overcurrent.
2) C2 should a low-impedance type capacitor.
A low-impedance type capacitor is recommended for C2 to ensure reduced ripple voltage and stable switching operation.
3. Diode D1
The Sanken AK06 diode is recommended for D1. If you intended to use an equivalent diode, be sure to use a Schottky Barrier diode and make
sure that the reverse voltage applied to terminal 2 of the IC does not exceed the value (–1V) given in the absolute maximum ratings. If you use
a fast recovery diode or any other diode, supplying a reverse voltage generated from the recovery or ON voltage of the diode may damage the
IC.
Application
Output voltage can be adjusted in the same way as SI-8000S in page 77.

Application Notes
1. Selecting External Components
(1) Choke coil L1
To maintain the stable operation of the regulator, choke coil L1
should be selected appropriately.
When selecting choke coil L1, consider the following:
a) Suitable for a switching regulator
Do not use a coil as a noise filter because it generates excess
heat.
b) Appropriate inductance
The greater the inductance of the choke coil, the smaller the
output ripple voltage. However, the size of the coil increases
large as the inductance increases. If the inductance is low, a
greater peak current flows to the IC and loss increases. This
is not favorable for stable operation.
The standard external circuit shows reference inductance values suitable for stable operation. However, the appropriate
inductance may also be calculated as follows:
(VIN–VO)•VO
L=
∆IL•VIN•f
Where, ∆IL indicates the ripple current of the choke coil that
is roughly set as follows:
• If the output current is close to the maximum rating (3 A) of
SI-8000S
Ripple current = output current × 0.2 to 0.3
• If the output current is about 1.0A or less
Ripple current = output current × 0.3 to 0.4
c) Satisfying the rated current
The rated current of a choke coil must be greater than the
maximum load current. Note that the inductance decreases
drastically and an excess current flows if the load current exceeds the rated current of the coil.
d) Good DC current superposition characteristics
The current flowing through a choke coil is a triangular waveform current superimposed on a DC current equal to the load
current. The coil inductance decreases as the load current
increases. In general, the coil can be used until the inductance drops to 50% of the rated value. Use this as the reference value for selection.
(2) Input capacitor C1
Input capacitor C1 operates as a bypass capacitor in the input
circuit.
When selecting input capacitor C1, consider the following:
a) The breakdown voltage is higher than the maximum input voltage.
b) Satisfies the allowable ripple current
Exceeding the ratings of this capacitor or using it without derating may reduce its service life and also cause the regulator
to malfunction. Therefore, an input capacitor with a sufficient
margin should be selected. With the SI-8000S Series, the
effective ripple current Irms flowing to the input capacitor can
be calculated approximately as follows:
VO
Irms 1.2 ×
× IO

(3) Output capacitor C2
Output capacitor C2 operates as a smoothing capacitor for switching output. The output ripple voltage from the regulator is determined by the product of the pulsating current part ∆IL (=C2 chargedischarge current) of the choke coil current and the equivalent
series resistance ESR of the output capacitor C2.
Vrip=∆IL•C2ESR
Therefore, a capacitor of low equivalent series resistance ESR
should be selected to reduce the output ripple voltage. It is recommended to select a low-impedance capacitor intended for use
with switching regulators as C2.
(4) Diode D1
Use a Schottky barrier diode for D1. If you use a general rectifier
diode or fast recovery diode, the IC may be damaged. (Sanken
RK46 recommended)
2. Cautions on Pattern Design
(1) Large current line
Since a large current flows through the bold lines in the standard
external circuit make the pattern as wide and as short as possible.

(2) Input capacitor
Place the input capacitor C1 and output capacitor C2 as close to
the IC as possible. Since a large current flows through the lead
wires of the input and output capacitors to charge and discharge
them quickly, minimize the lead wire length. The pattern around
the capacitors should also be minimized.

e) Less noise
A drum-type open magnetic core coil can affect peripheral
circuits with noise because the flux passes outside the coil.
To avoid this problem, use a toroidal, EI, or EE type closed
magnetic core coil.

(3) Sensing terminal
Output voltage sensing terminal VOS should be connected as close
to output capacitor C2 as possible. If the terminal is far from the
capacitor, the decreasing regulation and increasing switching
ripple may result in abnormal oscillation.
3. Variable Output Voltage
The output voltage can be increased by connecting a resistor to VOS
terminal No. 4. (There is no way of decreasing the voltage)

Applications
1. Soft Start
Connecting a capacitor to terminal no. 5 permits a soft start at poweron. Delay time Td and rise time Ts can roughly be calculated as
shown below. (However, the values may slightly vary in an actual
application.) If the capacitance of C3 is increased, it takes longer to
discharge C3 after VIN is turned off. Therefore, it is recommended to
set the value to 10µF or less. When not using the soft start function,
keep terminal no. 5 open.

* The temperature characteristics of output voltage worsen because
the value REX is not compensated for temperature. The Vs value
fluctuates by up to ±20% depending on the IC product. Since the
output voltage fluctuates more, a semi-fixed resistor is necessary
for accurate output voltage adjustment. If Vs and REX are constant,
the range of output voltage fluctuation can be expressed as follows:

2. Output ON/OFF control
Output can be turned on and off by using the soft start terminals.
Set the soft start terminal voltage to VSSL (0.2V typ.) or less to stop
output. To switch the potential at the soft start terminals, drive the
open collector of the transistor. Since the discharge current from C3
flows to the ON/OFF control transistor, limit the current for protection. The SS terminal is pulled up to the power supply in the IC and
no external voltage can be applied.

S:Stability factor
Bypassing the current to REX2 improves the temperature characteristics and voltage fluctuation ranges more than the method of
(1). Stability factor S indicates the ratio of REX1 to Vs terminal
inflow current. Increasing the S value improves the fluctuations
of the temperature characteristics and output voltage. (Usually 5
to 10)
If the Vs and REX values are constant, the output voltage fluctuation range can be calculated as follows:

The efficiency depends on the input
voltage and the output current. Thus,
obtain the value from the efficiency
graphs on p.81 and substitute the
percentage in the formula above.
■Caution
1. A low-impedance capacitor suitable for switching applications must be used for the external capacitor and must be connected as close to the
IC as possible in order to assure low ripple voltage and stable switching operation.
2. The SI-8200L and 8300L series do not have a built-in overcurrent protection circuit. Thus, avoid short-circuit conditions that may cause an
overcurrent.
3. The SI-8300L series may not start up if the input voltage rises too rapidly.
Do not use the SI-8300L series in applications where the input terminal, pin6, is opened and closed directly in a state where the input voltage
is already applied.
4. Terminals LIN and NC in the connection diagram must be left unconnected to other circuits.
5. The IC's metalic heatsink is electrically floating. Do not connect it to GND or any other circuit.
6. Since the SI-8200L and 8300L series have an open-package construction, they can only be used in specific environments. Verify the operating
environment and use the IC within the conditions indicated in the reliability data.

■SI-8500L application circuit
Terminal no.2 is for soft start. Connecting a capacitor to the terminal
enables the soft start function. See page 77 for the formulas to calculate delay time and rise time. Output can be turned on and off by
using the soft start terminal. To stop output, set the soft start terminal
voltage to VSSL (0.2V typ.) or less. To switch the potential of the soft
start terminal, drive the open collector of the transistor. Since the
discharge current from C3 flows to the ON/OFF control transistor, limit
the current for protection. The SS terminal is pulled up to the power
supply in the IC and no external voltage can be applied.

■Caution
1. Allocation of Components
For the best operating environment, the ground should be a single ground line at the GND terminal (terminal 2 on the SI-8400L, terminal 3 on
the SI-8500L), and the wiring from C1 and C2 to ground should be as short as possible.
2) C2 must be a low-impedance type capacitor to ensure minimum ripple voltage and stable switching operation.
3) C3 (SI-8500L only) is a capacitor for soft start. When not using soft start, leave terminal 2 open. It is pulled up inside the IC.
3. Terminals LIN and NC in the connection diagram must be left unconnected to other circuits.
4. The IC's metalic heatsink is electrically floating. Do not connect it to GND or any other circuit.
5. Since the SI-8400L and 8500L series have an open-package construction, they can only be operated in specific environments. Verify the
operating environment and use the conditions indicated in the reliability data.

■Caution
1. A low-impedance capacitor suitable for switching applications must be used for the external capacitor and must be connected as close to the
IC as possible in order to assure low ripple voltage and stable switching operation.
2. The SI-881L/8911L series does not have a built-in overcurrent protection circuit on VO2(–5V). Thus, avoid short-circuit conditions that may
cause an overcurrent.
3. Do not connect VIN(–) of SI-8811L to GND. The overcurrent protection circuit may not work if they are connected.
4. Terminals left unconnected in the connection diagram must not be connected to other circuits.
5. The IC's metallic heatsink is electrically floating. Do not connect it to GND or any other circuit.
6. Since the SI-8800L and 8900L series have an open-package construction, they can be operated in specific environments. Verify the operating
environment and use the IC within the conditions indicated in the reliability data.

and to secure it firmly to the heatsink.
The reliability of peripheral components such as capacitors and coils
is closely related to temperature. A high operating temperature may
reduce the service life. Exceeding the allowable temperature may
burn the coils or damage capacitors. It is important to make sure that
the temperature of output smoothing coils and input/output capacitors do not exceed their allowable levels during operation. Allow for
variation in the ratings of the coils and minimize heat emission as far
as possible. (For peripheral components, refer to the user manuals.)

●STA801M/802M
1. Inductors L1 and L2
(1) Suitable for switching regulators
Do not use a coil as a noise filter because it generates excess heat.
(2) Appropriate inductance
A low inductance may cause abnormal oscillation, or cause the overcurrent protection circuit to malfunction in the rated current range.
(3) Satisfying the rated current
Exceeding the rated current may generate an extremely high current to flow due to magnetic saturation.
2. Capacitors C1, C2, and C3
(1) Satisfy the breakdown voltage and allowable ripple current
Exceeding the ratings of these capacitors or using them without derating may shorten their service lives and also cause abnormal oscillation.
(2) Low impedance (C2, and C3)
A low-impedance model is recommended for C2 and C3 to reduce the ripple voltage and stabilize switching. For stable operation throughout
the input voltage range, however, the DC equivalent series resistance (ESR) of C2 and C3 should be 0.1 Ω or less.
(1) C4 and C5 are soft-start capacitors.
■Selecting Ch2 Output Voltage
When the VO2Cont terminal voltage is set to 0.5V or less, the output voltage changes to the values shown below. To switch the potential at the VO2Cont
terminal, drive the open collector of the transistor. No external voltage can be applied to the terminal. Leave the terminal open when not in use
because the terminal is already pulled up in the IC. When using terminal no. 9, short it to terminal no. 10.

■Soft Start ON/OFF Circuit
Terminal nos. 3 and 8 are soft start terminals. Connect a capacitor to the terminal to permit a soft start. Output can be turned on and off by using
the soft start terminals. Set the soft start terminal voltage to VSSL (0.15V) or less to stop the output. To switch the potential at the soft start terminals,
drive the open collector of the transistor. Since the discharge currents from C4 and C5 flow to the ON/OFF control transistor, limit the current for
protection. The SS terminal is pulled up to the power supply in the IC and no external voltage can be applied to the terminal.

: Input capacitor (Approx. 47µF)
This capacitor is required if the input line is inductive and in the case of long wiring.
When used at low temperature (–10° or less), set to 100µF or more or use tantalum capacitor.
: Delay time setting capacitor (0.1µF or more)
Use Cd to set the delay time (tDLY) from when a low VO level due to OCP operation is detected until a flag signal is output.
This prevents a rush current from causing malfunction at start.
Approximate calculation: tDLY (Cd × VDLYth)/IDLY[sec]
When using soft start on VIN or if CIN has a large capacitance, set tDLY long enough for the output voltage to rise sufficiently.
Be sure to connect Cd and do not use it for other applications, such as short circuiting Cd.

●SLA3001M/3002M/3004M
■Selecting External components for dropper type regulator
Input capacitor (Approx. 47µF)
Output capacitor (Approx. 47 to 100µF)
●Low ESR capacitors are recommended for input and output when using them in low temperature conditions (0°C or less)
■Selecting External components for switching type regulator
Input capacitor (Approx. 100µF)
Output smoothing capacitor (Approx. 330µF)
●Input capacitor and output capacitor must satisfy allowable ripple current.
●Low ESR capacitors are recommended for reducing output ripple voltage.
●Low ESR capacitors are recommended for input and output when using them in low temperature conditions (0°C or less)
Choke coil (200µH when VO is 3.3V or 5V, 300µH when VO is other)
●When its winding resistance is high, its efficiency may decrease and the rated value may not be achieved.
●Pay attention to heat from the choke coil due to magnetic saturation caused by overload, short circuit of load, etc. because the overcurrent
protection starting current is approx. 1A.
Flywheel diode (Sanken AK04 recommended)
●Use a Schottky barrier diode for D1, D2 and D3 and make sure that the reverse voltage applied to SW output terminal does not exceed the value
(–1V) given in the maximum ratings.
●If you use a fast recovery diode or any other diode, application of a reverse voltage generated from the recovery or ON voltage of the diode may
damage the IC.

*1 IS1 is specified at –5(%) drop point of output voltage VO on the condition that VIN = 7V, IO = 0.1A.
*2 Output is ON even when output control terminal VC is open. Each input level is equivalent to LS-TTL. Therefore, it may be directly driven by an
LS-TTL circuit.
*3 Total of four circuits
* The FLG output latched by delay DLY after OCP detection. (SLA3005M/SLA3007M (ch1 to 3) shuts down the output voltage simultaneously at
latching.) Set the VIN or VC to low to reset latching. Leave a time lag of Cd × 600s or more before restart.
** SLA3007Mch4 does not have the FLG output function.

: Input capacitor (Approx. 47µF)
This capacitor is required if the input line is inductive and in the case of long wiring.
: Delay time setting capacitor (0.1µF or more)
Use Cd to set the delay time (tDLY) from when a low VO level due to OCP operation is detected until a flag signal is output.
This prevents a rush current from causing malfunction at start.
Approximate calculation: tDLY (Cd × VDLYth)/IDLY[sec]
When using soft start on VIN or if CIN has a large capacitance, set tDLY long enough for the output voltage to rise sufficiently
Be sure to connect Cd and do not use it for other applications, such as short circuiting Cd.
: Reverse biasing protection diode
This diode is required for protection against reverse biasing of the input and output.
: Set this to limit the inflow current into the FLG terminal to 1mA or less.

■Calculating the Internal Dissipation
PD is calculated as follows:
PD=[IO1•(VIN-VO1)]+[IO2•(VIN-VO2)]+[IO3•(VIN-VO3)]+[IO4•(VIN-VO4)]+VIN•IG
■Estimating Tj by Temperature Measurement
1. Measuring position: At the root of pin 13
2. Add the thermal resistance "θj-L" between the junction and pin 13 and the Pd product of each channel to the measured temperature.
θj-L is as follows
: θj-L1:8°C/W, θj-L2:7°C/W, θj-L3:5°C/W, θj-L4:8°C/W
The calculation formula is as follows
:Tj=θj-L1•Pd1+θj-L2•Pd2+θj-L3•Pd3+θj-L4•Pd4+T13pin
