AZ431L

Description A Product Line of Diodes Incorporated AZ431L LOW VOLTAGE (1.24V) ADJUSTABLE PRECISION SHUNT REGULATOR Features 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%.  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/oC 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 +125oC These ICs are available in 4 packages: TO-92 (bulk or ammo packing), SOT-23, SOT-23-5 and SOT-89.
