ZTLV431
1.24V Cost effective shunt regulator
Description
Pin connections
The ZTLV431 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
volts and 10 volts by selection of two external divider resistors.

The ZTLV431 can be used as a replacement for zener diodes in many
applications requiring an improvement in zener performance.
