AZ431-B ADJUSTABLE PRECISION SHUNT REGULATORS Description Pin Assignments The AZ431-B 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. (Top View) (Top View) ANODE 3 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. Features  Programmable Precise Output Voltage from 2.5V to 18V  High Stability under Capacitive Load  Low Temperature Deviation: 4.5mV Typical  Low Equivalent Full-range 20PPM/°C Typical  Sink Current Capacity from 1mA to 100mA  Low Output Noise  Wide Operating Range of -40 to +125°C Temperature Coefficient Charger  Voltage Adapter  Switching Power Supply  Graphic Card  Precision Voltage Reference 2 REF CATHODE 1 2 3 REF ANODE CATHODE SOT-23 SOT-89 (Top View) (Top View) 3 CATHODE 3 CATHODE 2 ANODE 2 ANODE 1 REF 1 REF with TO-92 (Bulk Packing) TO-92 (Ammo Packing) (Top View) Applications  1 NC 1 * 2 CATHODE 3 5 ANODE 4 REF (Note 1) SOT-23-5 Note 1: * Pin 2 is attached to substrate and must be connected to ANODE or open AZ431-B Document number: DS41517 Rev. 4 - 2 1 of 15 www.diodes.com October 2018 © Diodes Incorporated AZ431-B Typical Applications Circuit VOUT=(1+R1/R2)*VREF Shunt Regulator VOUT=(1+R2/R3)*VREF High Current Shunt Regulator IOUT=VREF/R2+IKA Current Source or Current Limit AZ431-B Document number: DS41517 Rev. 4 - 2 2 of 15 www.diodes.com October 2018 © Diodes Incorporated AZ431-B Typical Applications Circuit (Cont.)
