ZTLV431
1.24V Cost effective shunt regulator
Description
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.
The ZTLV431 is available as standard as an A grade which has an initial
tolerance of 1%; a B grade is planned with an initial tolerance of 0.5%,
and all cover the -40°C to 125°C temperature range as standard.
