DESCRIPTION
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.
