DESCRIPTION
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 200m
Ω. 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.
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
200m
Ω;
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.
