H431 Series

HSMC Product Specification

H431 Series

H431 Series Pin Assignment

ADJUSTABLE SHUNT REGULATOR

Description

The H431 series are three-terminal adjustable regulators with guarante-ed

thermal stability over applicable temperature ranges. The output voltage

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
