LL431 Datasheet
PROGRAMMABLE PRECISION REFERENCE

 
DESCRIPTION
 
 The UTC LL431 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 VREF
(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 0.2Ω.
*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.
