GENERAL DESCRIPTION
The CM431A 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 18V by using two external resistors.
The CM431A offers low output impedance for improved load
regulation with a typical output impedance of 200mΩ. Because
of the active output circuitry, the CM431A 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.
Voltage Reference
Precision shunt regulator
High current shunt regulator
PWM down converter with reference
Voltage monitor
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 18V
Available in SOT-23, SOT-89, TO-92, & SOP-8
Low output noise
Typical equivalent full range temperature coefficient of
30ppm/
