LM431SA Datasheet (Fairchild Semiconductor) - Programmable Shunt Regulator

LM431SA, Programmable Shunt Regulator

The LM431SA/LM431SB/LM431SC are three terminal output adjustable regulators with thermal stability over operating temperature range.

The output voltage can be set any value between VREF (approximately 2.5 volts) and 36 volts with two external resistors.

These devices have a typical dynamic output im
