ZR431L
ADJUSTABLE PRECISION SHUNT REGULATOR Description Pin Assignments 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. (Top View) VREF 1 The devices can be used as a replacement for zener diodes in many
applications requiring an improvement in zener performance. 3 GND
VZ 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 3 volts. 2 SOT23 Features 2.5% and 1% Tolerance Max. Temperature Coefficient 50ppm/°C Applications Temperature Compensated for Operation over The Full
