AMC431
PRECISION ADJUSTABLE SHUNT VOLTAGE REFERENCE
FEATURES
The AMC431 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 AMC431 offers low output impedance for improved load regulation with a typical output impedance of 200mΩ. Because of the active output circuitry, the AMC431can 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.
