ADJUSTABLE PRECISION SHUNT REGULATORS
AZ431-B
General Description
The AZ431-B is a three-terminal adjustable shunt regu-
lator with guaranteed thermal stability over a full oper-
ation range. It features sharp turn-on characteristics,
low temperature coefficient and low output impedance,
which make it ideal substitute for Zener diode in appli-
cations such as switching power supply, charger and
other adjustable regulators.
The output voltage of AZ431-B can be set to any value
between VREF (2.5V) and the corresponding maximum
cathode voltage.
The AZ431-B precision reference is offered in two
voltage tolerance: 0.4% and 0.8%.
This IC is available in 5 packages: TO-92 (bulk or
ammo packing), SOT-23, SOT-23-5, SOT-89-3 and
SOIC-8.
