AMS431
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 0.08. 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.
