STL431 Datasheet, PDF (1/3 Pages) SeCoS Halbleitertechnologie GmbH – 3-Terminal Adjustable Shunt Regulator

Elektronische Bauelemente
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.
