The MET1117 series are highly accurate, low noise, LDO Voltage Regulators that are capable of providing an output current that is in excess of 800mA with a maximum dropout voltage of 1.7V at 800mA. This series contains six fixed output voltages of 1.2 V, 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 20 V with two external resistors. On chip trimming adjusts the reference/output voltage to within ¡À2.0% accuracy. Internal protection features consist of output current limiting, safe operating area compensation, and thermal shutdown. The MET1117 series can operate with up to 20 V input. Devices are available in SOT223£¬TO252-2L.
