AVANTICS - AX432 Series

Specification No.: 050308-FE0002

AX432 Series

Adjustable Shunt Regulator

Description

The AX432 series are three-terminal adjustable regulators with

guaranteed thermal stability over applicable temperature ranges. The

output voltage may be set to any value between V

or 1.25 volts) and 30 volts with two external resistors. These devices have

a typical dynamic output impedance of 0.2

Ω. Active output circuitry

provides a very sharp turn-on characteristic, making these devices

excellent replacement for zener diodes in many applications.

Features

• Programmable output voltage

• Temperature compensated for operation over full temperature range

• Low output noise voltage

• Fast turn on response
