AZ431-A
ADJUSTABLE PRECISION SHUNT REGULATORS
Description
Features
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.
The output voltage of AZ431-A can be set to any value between VREF
(2.5V) and the corresponding maximum cathode voltage (36V).
The AZ431-A precision reference is offered in two voltage tolerance:
0.4% and 0.8%.
This IC is available in 4 packages: TO92 (bulk or ammo packing),
SOT23, SOT25 and SOT89.
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
Sink Current Capacity from 1mA to 100mA
Low Output Noise
Wide Operating Range of -40 to +125oC
Lead-Free Packages: TO92, SOT23, SOT25, SOT89
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)
Applications
Charger
Voltage Adapter
Switching Power Supply
Graphic Card
Precision Voltage Reference
Notes:
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.
2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green"
and Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and
<1000ppm antimony compounds
