ZR431

ADJUSTABLE PRECISION ZENER SHUNT REGULATOR

Description

Pin Assignments

The ZR431 is a three terminal adjustable shunt regulator

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 20 volts by

selection of two external divider resistors.
