AMC431
PRECISION ADJUSTABLE
SHUNT VOLTAGE REFERENCE
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 V_REF
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.
FEATURES
„ Initial voltage reference accuracy of 0.5%,
1.0%, and 1.5%
„ Sink current capability from 1mA to 100mA
„ Typical output dynamic impedance less than
200mΩ;
„ Adjustable output voltage from VREF to 36V
„ Available in 3L-TO92 and surface mount SOT89,
SOT23.
„ Low output noise
„ Typical equivalent full range temperature
coefficient of 30ppm/°C
„ Pin assignment identical to earlier TL431 series.
APPLICATIONS
