DESCRIPTION

The UTC LL431 is a three-terminal adjustable regulator with a

guaranteed thermal stability over applicable temperature ranges.

(approximately 2.5V) and 36 V with two external resistors. It

can be used in 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 0.2

Ω.

*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.
