AZ431L Document number: DS36801 Rev. 4 - 2 1 of 20 www.diodes.com March 2018 © Diodes Incorporated AZ431L LOW VOLTAGE (1.24V) ADJUSTABLE PRECISION SHUNT REGULATOR Description The AZ431L series ICs are low voltage three-terminal adjustable regulators with guaranteed thermal stability over a full operation range. These ICs feature sharp turn-on characteristics, low temperature coefficient and low output impedance, which make them ideal substitutes for Zener diodes in applications such as switching power supply, charger, motherboard and other adjustable regulators. The output voltage can be set to any value between 1.24V and 18V with two external resistors. The AZ431L precision reference is offered in two voltage tolerance: 0.5% and 1.0%. These ICs are available in 4 packages: TO92 (bulk or ammo packing), SOT23, SOT25 and SOT89. Features  Wide Programmable Precise Output Voltage from 1.24V to 18V  High Stability under Capacitive Load  Low Temperature Deviation: 3mV Typical  Low Equivalent Full-range Temperature Coefficient: 20PPM/°C Typical  Low Dynamic Output Resistance: 0.05Ω Typical  High Sink Current Capacity from 0.1mA to 100mA  Low Output Noise  Wide Operating Range of -40 to +125°C  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  Graphic Card  PC Motherboard  Voltage Adapter  Switching Power Supply  Charger Pin Assignments (Top View) (Top View) TO92 (Bulk Packing) TO92 (Ammo Packing) (Top View) (Top View) SOT23 SOT25 Note 4: *Pin 2 is attached to substrate and must be connected to ANODE or open. (Top View) (Top View) SOT89 (Option 1) SOT89 (Option 2) Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant. 2. See https://www.diodes.com/quality/lead-free/ 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. 1 2 3 CATHODE ANODE REF CATHODE ANODE REF 3 21 CATHODE ANODE REF 1 2 3 4 5NC * (Note 4) CATHODE ANODE REF1 2 3 1 2 3 REF ANODE CATHODE 1 2 3 REF ANODE CATHODE
