ZENER SHUNT REGULATOR

Issue 1 - NOVEMBER 1998

ZR431L

DEVICE DESCRIPTION

FEATURES

The ZR431L is a three terminal adjustable

shunt regulator offering excellent

temperature stability and output current

handling capability up to 25mA. The output

voltage may be set to any chosen voltage

between 1.24 and 10 volts by selection of

two external divider resistors.

Surface mount SOT23 package

TO92 package

•

2.5% and 1% tolerance

Maximum temperature coefficient 50

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.

Programmable output voltage

100µA to 25mA current sink capability

Low output noise

•

The ZR431L is particularly used in the

feedback control loop of switch mode power

supplies. In this application the device 1.24

volt reference enables the generation of low

voltage supplies, typically 3.3 volts or 3volts.

APPLICATIONS

Shunt regulator

•

Series regulator

•

Voltage monitor

•

Over voltage/ under voltage protection

•

Switch mode power supplies
