Description
The AMS431 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 36V with two external resistors. This device has a typical output impedance of 0.08Ω. Active output circuitry provides a very sharp turn on characteristic, making this device excellent replacement for Zener diodes in many applications.
The AMS431 is characterized for operation from -40oC to 125oC, 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.
