ACE432A

www.DataSheet4U.com ACE432A Technology Description Precision adjustable shunt voltage reference The ACE432 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 ACE432 precision reference is offered in two voltage tolerance: 0.5% and 1.0%. These ICs are available SOT-23-3. 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/℃ 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℃ Application Graphic Card PC Motherboard Voltage Adapter Switching Power Supply Charger Absolute Maximum Ratings Parameter Cathode to Anode Voltage (Note 2) Cathode Current Range (Continuous) Reference Input Current Range Power Dissipation Junction Temperature Storage temperature range Symbol VKA IKA IREF PD TJ TSTG Max Unit 20 V -100 to 100 mA 10 370 150 - 65 to 150 mA mW O O C C Note 1: Stresses greate...
