GTL431
Description
Adjustable Shunt Regulator
The GTL431 series are three-terminal adjustable regulators with guaranteed thermal stability over applicable temperature ranges.
The output voltage may be set to any value between V
REF
(approximately 2.495v) and 36v with two external resistors.
It provides very wide applications, including shunt regulator, series regulator, switching regulator, voltage reference and others.
