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
2.495 volts) and 36 volts with two external resistors. These devices
have a typical dynamic output impedance of 0.2
. Active output circ-
uitry provides a very sharp turn-on characteristic, making these devices excellent replacement for
zener diodes in many applications.
