HSMC Product Specification

H431AM/BM/CM

AJDUSTABLE SHUNT REGULATOR

Description

The H431XM series are three-terminal adjustable regulators with gu-

aranteed thermal stability over applicable temperature ranges. The

2.495 volts) and 36 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 replacem-

ent 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
