AP431/AP431A
ADJUSTABLE PRECISION SHUNT REGULATOR
Description
The AP431 and AP431A are 3-terminal adjustable precision shunt
regulators with guaranteed temperature stability over the applicable
extended commercial temperature range. The output voltage may be
set at any level greater than 2.495V (V
REF
) up to 36V merely by
selecting two external resistors that act as a voltage divider network.
These devices have a typical output impedance of 0.2Ω. Active output
circuitry provides very sharp turn-on characteristics, making these
devices excellent improved replacements for Zener diodes in many
applications.
