1. Variable output voltage with a single external resistor
The output voltage may be increased by inserting resistor R
EX
between
terminals No.4 (sensing terminal) and No.3 (output terminal). The cur-
rent I
REX
flowing into terminal No.4 is 1mA (typ.)(SI-3033C:0.43mA (typ.)),
therefore the adjusted output voltage V
OUT
is:

: output voltage of SI-3000C 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.
2. Variable output voltage with two external resistors
The output voltage may be increased by inserting resistors R
EX1
be-
tween terminals No.4 (sensing terminal) and No.3 (output terminal) and
R
EX2
between terminals No.4 and No.1 (ground terminal).
The current I
4IN
flowing into terminal No.4 is 1mA (typ.)(SI-3033C:
0.43mA (typ.)) so the thermal characteristics may be improved com-
pared to the method shown in 1 by setting the external current I
REX1
at
approximately 5 times the value of I
4IN
(stability coefficient S=5).
The adjusted output voltage V

in this case is:

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 V
04
, the necessary
output current may not be obtained due to the S.O.A. protection
circuit in the SI-3000C series.
