The CM431 is a three-terminal adjustable shunt voltage regulator
with specified thermal stability and pin-to-pin compatible with the
earlier 431 series. The output voltage can be adjusted to any
value between V

REF
CM431 offers low output impedance for improved load regulation
with a typical output impedance of 200m
Ω
. Because of the
active output circuitry, the CM431 can replace the zener diodes in
applications such as switching power supplies, OVP crowbar
circuits, references for A/D, D/A converters with improved turn-on
characteristics.
