GM432
1.24V ADJUSTABLE PRECISION
SHUNT REGULATORS
Description
The GM432 is a low-voltage three-terminal
adjustable precision shunt regulator with
specified thermal stability over full temperature
range. Output voltage can be set to any value
from Vref (1.24V) to 16V by using two external
resistors. The active output circuitry provides a
very unique turn-on characteristic, making them
excellent replacements 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 suppliers.
GM432 is available in SOT23, TO92 and SOT89
packages.
