CM431 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 VREF and 36V by using two external resistors. The CM431 offers low output impedance for improved load regulation with a typical output impedance of 200m. 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.

CM431 Maximum Ratings

Cathode to Anode Voltage (VKA) (Note 2)	-0.3V to 37V
Continuous Cathode Current (IK)	-100mA to 150mA
Reference Input Current (IREF)	-50uA to 10mA
Maximum junction temperature range, TJ	150
Storage temperature range	-65 to 150
Lead temperature (soldiering, 10 seconds)	260
Note 1: Exceeding these ratings could cause damage to the device. All voltages are with respect to Ground. Currents are positive into, negative out of the specified terminal. Note 2: Voltage values are with respect to the anode terminal unless otherwise noted.
