TLV431A Datasheet

TLV431A Low-Voltage Adjustable Precision Shunt Regulator

The TLV431 device is a low-voltage 3-terminal adjustable voltage reference with specified thermal stability over applicable industrial and commercial temperature ranges. Output voltage can be set to any value between VREF (1.24V) and 6V with two external resistors (see the Parameter Measurement Inf.
