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-

put voltage may be set to any value between V

REF

(approximately

TO-92

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

have a typical dynamic output impedance of 0.2Ω. Active output circ-

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

zener diodes in many applications.
