NCP1117ST33T3G Datasheet

Low Dropout Regulators - LDO


The NCP1117ST33T3G series are low dropout positive voltage regulators thatare capable of providing an output current that is in excess of 1.0 Awith a maximum dropout voltage of 1.2 V at 800 mA overtemperature. This series contains nine fixed output voltages of 1.5 V,1.8 V, 1.9 V, 2.0 V, 2.5 V, 2.85 V, 3.3 V, 5.0 V, and 12 V that have nominimum load requirement to maintain regulation. Also included is anadjustable output version that can be programmed from 1.25 V to18.8 V with two external resistors. On chip trimming adjusts thereference/output voltage to within 1.0% accuracy. Internal protectionfeatures consist of output current limiting, safe operating areacompensation, and thermal shutdown. The NCP1117 series canoperate with up to 20 V input. Devices are available in SOT−223 andDPAK packages.
