DESCRIPTION

The TJ431 is a three-terminal adjustable shunt regulator with specified thermal stability over applicable temperature VREF (Approx. 2.5V) and 28V with two external resistors. This device has a typical dynamic output impedance of 0.25ohm. Active output circuitry provides a very sharp turn-on characteristic, making this device excellent replacement for zener diodes in many applications. The TJ431 is characterized for operation from -40°C to +125°C.
