Adjustable Precision Shunt Regulators
Product Description
The GS432 is a 3 terminal adjustable voltage
reference with specified thermal stability over
applicable commercial temperature ranges.
Output voltage may be set to any value
between V REF (1.24V) and 16V with two
external resistors (see Figure 2). When used
with a photo-coupler, the GS432 is an ideal
voltage reference in isolated feedback circuits
for 1.24V to 16V switching-mode power
supplies.
This device has a typical output impedance of
0.05. Active output circuitry provides a very
sharp turn-on characteristic, making the
GS432 excellent replacements for zener
diodes in many applications, including
on-board regulation and adjustable power
supplies.
