DESCRIPTION
The UTC TL431 is a three-terminal adjustable regulator with a
guaranteed thermal stability over applicable temperature ranges.
The output voltage may be set to any value between V
REF
(approximately 2.5V) and 36V with two external resistors. It provides
very wide applications, including shunt regulator, series regulator,
switching regulator, voltage reference and others.
FEATURES
* Programmable output Voltage to 36V.
* Low dynamic output impedance 0.2Ω.
* Sink current capability of 1.0 to 100mA.
* Equivalent full-range temperature coefficient of 50ppm/ °C
typical for operation over full rated operating temperature range.
