AZ431-A
ADJUSTABLE PRECISION SHUNT REGULATORS
Description
Features
Programmable Precise Output Voltage from 2.5V to 36V
High Stability under Capacitive Load
Low Temperature Deviation: 4.5mV Typical
Low Equivalent Full-range Temperature Coefficient with
20PPM/oC Typical
The AZ431-A is a three-terminal adjustable shunt regulator with
guaranteed thermal stability over a full operation range. It features
sharp turn-on characteristics, low temperature coefficient and low
output impedance, which make it ideal substitute for Zener diode in
applications such as switching power supply, charger and other
adjustable regulators.
Sink Current Capacity from 1mA to 100mA
Low Output Noise
Wide Operating Range of -40 to +125oC
Lead-Free Packages: TO92, SOT23, SOT25, SOT89
The output voltage of AZ431-A can be set to any value between VREF
(2.5V) and the corresponding maximum cathode voltage (36V).
.
Totally Lead-Free; RoHS Compliant (Notes 1 & 2)
Lead-Free Packages, Available in “Green” Molding Compound:
TO92, SOT23, SOT25, SOT89
.
.
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
The AZ431-A precision reference is offered in two voltage tolerance:
0.4% and 0.8%.
Applications
This IC is available in 4 packages: TO92 (bulk or ammo packing),
SOT23, SOT25 and SOT89.
