TL431/TL432
ADJUSTABLE PRECISION SHUNT REGULATOR
Description
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.
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
