GTL431
Adjustable Shunt Regulator
Description
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 VREF (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.
