GENERAL DESCRIPTION
CM431
LOW VOLTAGE ADJUSTABLE SHUNT
REGULATOR
FEATURES
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 VBREFB and 36V by using two external resistors. The 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.
