Overview
The LM431 is a three-terminal adjustable shunt regulator with specified thermal stability over applicable temperature V_REF (2.5V) and 40V with two external resistors. This device has a typical dynamic output impedance of 0.2Ω. Active output circuitry provides a very sharp turn-on characteristic, making this device excellent replacement for Zener diodes in many applications. The LM431 is characterized for operation from - 40°C to +125°C.
Applications
