H431AA/BA/CA

AJDUSTABLE SHUNT REGULATOR

Description

The H431 series are three-terminal adjustable regulators with guara­nteed thermal stability over applicable temperature ranges. The out­put voltage may be set to any value between VREF (approximately

2.495 volts) and 36 volts with two external resistors. These devices
have a typical dynamic output impedance of 0.2Ω. Active output circ­uitry provides a very sharp turn-o n ch aracteristic, maki ng these dev ices excell ent replac ement 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
