TLV431

1.24V Cost effective shunt regulator

Description

The TLV431 is a three terminal adjustable shunt

regulator offering excellent temperature

stability and output current handling capability

up to 20mA. The output voltage may be set to

any chosen voltage between 1.24 and 18 volts

by selection of two external divider resistors.

CATHODE

The TLV431 can be used as a replacement for

zener diodes in many applications requiring an

improvement in zener performance.
