Product Overview
TL431ASA-7 is a three terminal adjustable shunt regulator. It offers 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 36volts by selection of two external divider resistors. The device can be used as a replacement for Zener diodes in many applications requiring an improvement in Zener performance. Typical applications include opto-coupler linearisers, shunt regulators, improved Zener, variable reference.
