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.)(SI-3033C:0.43mA (typ.)),
therefore the adjusted output voltage VOUT is:
VO=V04+IREX•REX
*V04: output voltage of SI-3000C series
However, the built-in 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.)(SI-3033C:
0.43mA(typ.)) so the thermal characteristics may be improved compared
to the method shown in 1 by setting the external current IREX1 at ap-
proximately 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-3000C 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-3000C series.
