Advanced Monolithic Systems FEATURES Three Terminal Adjustable or Fixed Voltages 1.5V, 2.5V, 2.85V, 3.0V, 3.3V, 3.5V and 5.0V Output Current of 3A Operates Down to 1V Dropout Load Regulation: 0.1% Line Regulation: 0.015% TO-220, TO-263 and TO-252 packages available AMS1085 3A LOW DROPOUT VOLTAGE REGULATOR RoHS compliant APPLICATIONS High Efficiency Linear Regulators Post Regulators for Switching Supplies Microprocessor Supply Battery Chargers Constant Current Regulators Notebook/Personal Computer Supplies Portable Instrumentation GENERAL DESCRIPTION TThhee AMS1085 series of adjustable and fixed voltage regulators are designed to provide 3A 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 AMS1085 devices are pin compatible with older three-terminal regulators and are offered in 3 lead TO-220 package, 3 and 2 lead TO-263 (Plastic DD) and TO-252 (D PAK) package.
