Description

The LM431A/LM431B/LM431C are three terminal output adjustable regulators with thermal stability over operatingtemperature 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 dynamicoutput impedance of 0.2Ω Active output circuit provides a sharp turn-on characteristic, making these devices excellent replacement for Zener Diodes in many applications.
