Description
The GM432's are low-voltage three-terminal adjustable pre-
cision shunt regulators with specified thermal stability over
their full temperature range. Output voltage can be set to
any value from V
(1.24V) to 16V by using two external
ref
resistors. Their active output circuitry provides a very
unique turn-on characteristic, making them excellent re-
placements for zener diodes in many applications such as
onboard regulation and adjustable power supplies. In a
wide range of home applications, these versatile darlings
are ideal voltage references for 3.0V to 3.3V switching
power suppies. With operational cathode current as low as
80A, batteries keep on going. Whatever your application
is, the GM432's offer the optimum combination of perfor-
mance, reliability, and economy.
