TL431A ADJUSTABLE PRECISION SHUNT REGULATOR

TL431A ADJUSTABLE PRECISION SHUNT REGULATOR

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.
