Adjustable/2.5V, 0.5% Tolerance Shunt Regulator

The LM431A LM431B LM431C are three-terminal output adjustable Regulators with thermal stability over operating temperature range. The output voltage CAN be set any value between VREF (approximately 2.5 volts) and 36 volts with two external resistors. These devices have a typical dynamic output impedance of 0.2W. Active output circuit provides a sharp turn-on characteristic, making these devices excellent replacement for Zener Diodes in many applications.
