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
output voltage may be set to any value between V
REF
(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-on characteristic, making these devices excellent replacem-
ent for zener diodes in many applications.
