PART OBSOLETE - USE AZ431L AZ432 OBSOLETE – PART DISCONTINUED LOW VOLTAGE (1.25V) ADJUSTABLE PRECISION SHUNT REGULATOR Description Features The DIODES™ AZ432 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 1.25V and 18V with two external resistors. The AZ432 precision reference is offered in two voltage tolerance: 0.5% and 1.0%. These ICs are available in 4 packages: TO-92 (bulk or ammo packing), SOT-23, SOT-23-5 and SOT-89. Wide Programmable Precise Output Voltage from 1.25V 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 For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/104/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative. https://www.diodes.com/quality/product-definitions/ Applications      Graphic cards PC motherboards Voltage adapters Switching power supplies Chargers Pin Assignments (Top View) (Top View) (Top View) ANODE 3 CATHODE 3 CATHODE 2 ANODE 2 ANODE 1 REF 1 REF TO-92 (Bulk Packing) 1 * 2 CATHODE 3 (Note 1) 5 ANODE 4 REF Note: 2 REF CATHODE SOT-23 (Top View) (Top View) 1 2 3 REF ANODE CATHODE SOT-23-5 1 TO-92 (Ammo Packing) (Top View) NC 3 SOT-89 (Option 1) 1 2 3 REF ANODE CATHODE SOT-89 (Option 2) 1.
