ME1117 series are highly accurate, low noise,LDO Voltage Regulators that are capable of providingan output current that is in excess of 1.0A with amaximum dropout voltage of 1.3V at 1.0A. This seriescontains six fixed output voltages of 1.2 V, 1.5V,1.8 V,2.5 V, 3.3 V, and 5.0 V that have no minimum loadrequirement to maintain regulation. Also included is anadjustable output version that can be programmedfrom 1.25 V to 20 V with two external resistors. Onchip trimming adjusts the reference/output voltage towithin ?2.0% accuracy. Internal protection featuresconsist of output current limiting, safe operating areacompensation, and thermal shutdown. The ME1117series can operate with up to 20 V input.
