DESCRIPTION
ADJUSTABLE PRECISION SHUNT
REGULATOR
AP432
SE432
FEATURES
Low voltage operation (1.24V)
Adjustable output voltage V
0
=V
REF
to 12V
Wide operating current range 55µA to 100mA
Low dynamic output impedance 0.25Ω typ.
ESD rating is 6KV(Per MIL-STD-883D).
The AP432 is a low voltage three terminal adjustable shunt
regulator with a guaranteed thermal stability over
applicable temperature ranges. The output voltage can be
set to any value between V
REF
(approximately 1.24 V) to
12V with two external resistors (see application circuit).
This device has a typical output impedance of 0.25Ω.
Active output circuitry provides a very sharp turn on
characteristic, making this device excel lent replacement
for Zener diodes in many applications.
The AP432 is characterized for operation from 0 C to
105 C, and four package options (SOT-23, SOT-89, SO-8
and TO-92) allow the designer the opportunity to select the
proper package for their application.
