Description

The SE431 is a low voltage three terminal adjustable shunt regulator with a guaranteed thermal stability over applicable temperature ranges. The output voltage can be set to any value between VREF (approximately 2.5 V) to 18V with two external resistors.This device has a typical output impedance of 0.2.Active output circuitry provides a very sharp turn on characteristic, making this device excellent replacement for Zener diodes in many applications.

The SE431 is characterized for operation from 0to 105, and five package options (SOT-23-3, SOT-23-5,SOP-8, TO-92 and SOT-89) allow the designer the opportunity to select the proper package for their applications.
