低压差线性稳压IC

The MET1117 series are highly accurate, low noise, LDO Voltage Regulators that are capable of providing an output current that is in excess of 700mA with a maximum dropout voltage of 1.5 V at 700mA. This series contains six fixed output voltages of 1.2 V,1.8 V, 2.5V, 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 %2B2 .0% accuracy Internal protection features consist of output current. limiting，safe operating area compensation, and thermal shutdown. The MET 1117 series can operate with up to 20 V input. Devices are available in SOT223，TO252-2L.
