Description	Programmable Shunt Regulator
Datasheet	LM431A-ONSemiconductor.pdf

The LM431A/LM431B/LM431C are three−terminal output adjustable regulators with thermal stability over the full operating temperature range.

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

These devices have a typical dynamic output impedance of 0.2 W.

Programmable Output Voltage to 36 V.
Low Dynamic Output Impedance: 0.2 W (Typical).
Sink Current Capability: 1.0 to 100 mA.
Equivalent Full.
Range Temperature Coefficient of 50 ppm/°C (Typical).
Temperature Compensated for Operation Over Full Rated Operating Temperature Range.
Low Output Noise Voltage.
Fast Turn.
