ZH431 Overview

ADJUSTABLE PRECISION ZENER SHUNT REGULATOR

ADJUSTABLE PRECISION
ZENER SHUNT REGULATOR
Issue 2 - February 1998
DEVICE DESCRIPTION
The ZH431 is a three terminal adjustable
s hu n t r e g u l a t or o f f e r i n g e xc el l e nt
temperature stability and output current
handling capability up to 30mA. The output
voltage may be set to any chosen voltage
between 2.5 and 36 volts by selection of two
external divider resistors.
The devices can be used as a replacement
for zener diodes in many applications
r e qu i r i n g a n i mpr o ve me nt i n z e ner
performance.They are also ideal for use in
the feedback circuits of off line SMPUs as
well as many general purpose regulator and
reference applications where initial accuracy
and low temperature coefficient are key
requirements.
Note:
ZH431 is not recommended for new designs.
