S-LR431XXKLT1G
DESCRIPTION
The
S-LR431 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
36V with two external resistors. It provides very
wide applications, including shunt regulator, series
regulator, switching regulator, voltage reference and
others.
