The KF1117 series are highly accurate, low noise, LDO Voltage Regulators that are capable of providing an output current that is in excess of 1.0 A with a maximum dropout voltage of 1.3 V at 1.0A. This series contains six fixed output voltages of 1.2V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V that have no minimum load requirement to maintain regulation. Also included is an adjustable output version that can be programmed from 1.25 V to 15 V with two external resistors. On chip trimming adjusts the reference/output voltage to within 土2.0% accuracy. Internal protection voltage to within 土2.0% accuracy. Internal protection area compensation, and thermal shutdown. The KF1117 series can operate with up to 15 V input. Devices are available in SOT223，TO252-2L.
