GENERAL DESCRIPTION
CM431A
LOW VOLTAGE ADJUSTABLE SHUNT
REGULATOR
FEATURES
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 VREF 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.
