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 and 8 pin S.O.I.C. packages
#
Low output noise
#
Typical equivalent full range temperature
coefficient of 30ppm/°C
#
Pin assignment identical to earlier TL431
series.
