CM1117FCM223

CM1117F 1A LOW DROPOUT VOLTAGE REGULATOR GENERAL DESCRIPTION The CM1117F series of adjustable and fixed voltage regulators are designed to provide 1A for applications requiring high efficiency. All internal circuitry is designed to operated down to 1V input to output differential and the dropout voltage is fully specified as a function of load current. The CM1117F offers current limiting and thermal protection. The on chip trimming adjusts the reference voltage accuracy to2%. FEATURES Three Terminal Adjustable or Fixed Voltages: 1.8V, 2.5V, 3.3V, and adjustable. Output Current of 1A Low dropout voltage: 1.1V Typ. Line Regulation: 0.3% Max Load Regulation: 2% Max Fast Transient Response Thermal Protection SOT-223 package available Rugged 3KV ESD withstand capability.
