*1: "A" may be indicated to the right of the Sanken logo.
*2: VIN(max) and IO(max) are restricted by the relation PD(max)=(VIN-VO)•IO=14W(SI-3240F: 18W).
*3: Refer to the dropout voltage.(Refer to Setting DC Input Voltage on page 7.)
*4: IS1 is specified at –5(%) drop point of output voltage VO on the condition that VIN=VO+3V, IO=0.5A.
*5: 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.
*6: When setting output voltage to 5V or less, input voltage needs to be set to 6V or over to operate stably.
*7: A foldback type overcurrent protection circuit is built into the IC regulator.Therefore, avoid using it for the following applications as it may cause
starting errors:
(1) Constant current load (2) Plus/minus power (3) Series power (4) VO adjustment by raising ground voltage

The output voltage may be increased by inserting resistor REX between
terminals No.4 (sensing terminal) and No.3 (output terminal). The cur-
rent 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 characteris-
tics of +0.2%/°C.
It is important to keep the thermal characteristics in mind when adjust-
ing the output voltage.

The output voltage may be increased by inserting resistors REX1 be-
tween 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

Note: In the SI-3000F series, the output voltage increase can be ad-
justed as mentioned above. However, when the rise is set to ap-
proximately 10V compared to output voltage V04, the necessary
output current may not be obtained due to the S.O.A. protection
circuit in the SI-3000F series.

Note on Thermal Protection:
The thermal protection circuit is intended for
protection against heat during instantaneous

teed for continuous heating condition such
as short-circuiting over extended periods of
time.
