ADJUSTABLE PRECISION SHUNT REGULATORS
General Description
Features
AZ431-B
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 4 packages: TO-92 (bulk or
ammo packing), SOT-23, SOT-23-5 and SOT-89.
· Programmable Precise Output Voltage from 2.5V
to 18V
· High Stability under Capacitive Load
· Low Temperature Deviation: 4.5mV Typical
· Low Equivalent Full-range Temperature Coeffi-
cient with 20PPM/oC Typical
· Sink Current Capacity from 1mA to 100mA
· Low Output Noise
· Wide Operating Range of -40 to 125oC
Applications
· Charger
· Voltage Adapter
· Switching Power Supply
· Graphic Card
· Precision Voltage Reference
