1.24V ADJUSTABLE PRECISION SHUNT REGULATORS

Features

Description

Low-voltage operation, down to 1.24V

0.5%, 1% or 2% reference voltage tolerance

Adjustable output voltage, V = V to 16V

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

ref

any value from V

(1.24V) to 16V by using two external

ref

Sink Current Capability 80µA to 100mA

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

80µA, batteries keep on going. Whatever your application

is, the GM432's offer the optimum combination of perfor-

mance, reliability, and economy.

Low dynamic output impedance, 0.05W typical

Wide temperature range, 0° to +70°C

Pin-to-pin replacement for TLV431, SC431L

Available in SOT-23, SOT-25, SOT-89, TO-92

and SOP-8
