AP431/AP431A
ADJUSTABLE PRECISION SHUNT REGULATOR
Description
Pin Assignments
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 (VREF) 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.
