DESCRIPTION
The UTC
TL431
is a three-terminal adjustable regulator with a
guaranteed thermal stability over applicable temperature ranges.
The output voltage may be set to any value between V
REF
(approximately 2.5V) and 36V with two external resistors. It provides
very wide applications, including shunt regulator, series regulator,
switching regulator, voltage reference and others.
