GENERAL DESCRIPTION
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
and 36V by using two external resistors. The

FEATURES
Initial voltage reference accuracy of 1.0%.
Sink current capability from 1mA to 100mA
Typical output dynamic impedance less than 200mΩ;
Adjustable output voltage from V
REF
to 36V

CM431 offers low output impedance for improved load regulation
with a typical output impedance of 200mΩ.
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.
Available in SOT-23, SOT-89, TO-92, & SOP-8
Low output noise
Typical equivalent full range temperature coefficient of
30ppm/
