HSMC Product Specification

H431AA/BA/CA

AJDUSTABLE SHUNT REGULATOR

Description

The H431 series are three-terminal adjustable regulators with guara-

nteed thermal stability over applicable temperature ranges. The out-

2.495 volts) and 36 volts with two external resistors. These devices

have a typical dynamic output impedance of 0.2

Ω. Active output circ-

uitry provides a very sharp turn-on characteristic, making these devices excellent replacement for

zener diodes in many applications.

Features

• Programmable output voltage

• Temperature coefficient is 50ppm/°C typical

• Temperature compensated for operation over

• full temperature range

• Low output noise voltage

• Fast turn on response
