Product Summary

The ncp1117dt33rkg is a low dropout positive voltage regulator that is capable of providing an output current that is in excess of 1.0 A with a maximum dropout voltage of 1.2 V at 800 mA over temperature. The ncp1117dt33rkg 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 no minimum load requirement to maintain regulation. Also included is an adjustable : resistors. On chip trimming adjusts the reference/output voltage to within ±1.0% accuracy. Internal protection features of the ncp1117dt33rkg consist of output current limiting, safe operating area compensation, and thermal shutdown. The ncp1117dt33rkg can operate with up to 20 V input. Devices are available in SOT-223 and DPAK packages. Applications are: (1)Consumer and Industrial Equipment Point of Regulation; (2)Active SCSI Termination for 2.85 V Version; (3)Switching Power Supply Post Regulation; (4)Hard Drive Controllers; (5)Battery Chargers.
