ADJUSTABLE PRECISION

ZENER SHUNT REGULATOR

Issue 2 - February 1998

ZH431

DEVICE DESCRIPTION

FEATURES

The ZH431 is a three terminal adjustable

shunt regulator offering excellent

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.

Surface mount SO8, SOT223,SOT23

and SOT89 packages

•

TO92 package

•

2% and 1% tolerance

Maximum temperature coefficient 55

ppm/°C

Temperature compensated for

operation over the full temperature

range

•

The devices can be used as a replacement

for zener diodes in many applications

requiring an improvement in zener

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 initialaccuracy

and low temperature coefficient are key

requirements.

Programmable output voltage

50µA to 30mA current sink capability

Low output noise

•

APPLICATIONS

Shunt regulator

•

Note:

Series regulator

•

ZH431 is not recommended for new designs.

Refer to ZR431

Voltage monitor

•

Over voltage/ under voltage protection

•

Switch mode power supplies

•
