The ME1117A50B3G is a Low Dropout Regulator (LDO) Positive Fixed 1.4V @ 1A 20V 5V 1A SOT-223 RoHS manufactured by Micro One. This part is designed to regulate output voltage within an operating range of 1.2V to 20V, while consuming a very low quiescent current making it suitable for battery-powered applications. Its dropout voltage is low at less than 0.4V at light loads, and it provides excellent line, load and temperature regulation. It also features current limiting and thermal shutdown protection, as well as an output voltage tolerance of ±5%. The SOT-223 RoHS package provides low thermal resistance, small physical size and increased power dissipation when compared to standard SOT-223 packages. This versatile, highly reliable part is ideal for use in a variety of applications such as cell phone base station amplifiers, USB ports, PC card socket voltage regulators, laser and welding power supplies, high performance voltage regulation and circuit protection.
