TL431/TL432

ADJUSTABLE PRECISION SHUNT REGULATOR

Description

Pin Assignments

TL431

(Top View)

The TL431 and TL432 are three terminal adjustable shunt

regulators offering excellent temperature stability and output

current handling capability up to 100mA. The output voltage

may be set to any chosen voltage between 2.5 and 36 volts

by selection of two external divider resistors.

REF

ANODE

The devices can be used as a replacement for zener diodes

in many applications requiring an improvement in zener

performance. Diodes’ TL431 has the same electrical

specifications as the industry standard ‘431 and is available

in 2 grades with initial tolerances of 1% and 0.5% for the

A and B grades respectively.
