AMS317

Advanced Monolithic Systems AMS317 1A LOW DROPOUT VOLTAGE REGULATOR RoHS compliant FEATURES Three Terminal Adjustable or Fixed Voltages* 1.8V, 2.5V, 2.85V, 3.3V and 5.0V Output Current of 1A Operates Down to 1V Dropout Line Regulation: 0.2% Max. Load Regulation: 0.4% Max. TO-220, TO-263, TO-252 and SOT-223 package available APPLICATIONS High Efficiency Linear Regulators Post Regulators for Switching Supplies 5V to 3.3V Linear Regulator Battery Chargers Active SCSI Terminators Power Management for Notebook Battery Powered Instrumentation GENERAL DESCRIPTION TThhee AMS317 series of adjustable and fixed voltage regulators are designed to provide 1A output current and to operate down to 1V input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.3V at maximum output current, decreasing at lower load currents. On-chip trimming adjusts the reference voltage to 1%. Current limit is also trimmed, minimizing the stress under overload conditions on both the regulator and power source circuitry. The AMS317 devices are pin compatible with other three-terminal regulators and are offered in 3 lead TO-220 package, in the 2 & 3 Lead TO-263 (Plastic DD), in the TO-252 (D PAK) and in the low profile surface mount SOT-223 package.
