Description

The STL431 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.
