CM1117 1A LOW DROPOUT VOLTAGE REGULATOR GENERAL DESCRIPTION The CM1117 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 800mV input to output differential and the dropout voltage is fully specified as a function of load current. The CM1117 offers current limiting and thermal protection. The on chip trimming adjusts the reference voltage accuracy to 1%. FEATURES Three Terminal Adjustable or Fixed Voltages: 1.8V, 2.5V, 3.3V, and adjustable. Output Current of 1A Low dropout voltage: 1V Typ. Line Regulation: 0.2% Max Load Regulation: 0.4% Max Fast Transient Response Thermal Protection SOT-223 and TO-252 package available APPLICATIONS High Efficiency Linear Regulators Post Regulators for Switching Supplies Battery Chargers Active SCSI Terminators Post Regulator for Switching DC/DC Converter Battery Powered Instrumentation PIN CONFIGURATION TO-252 Front View V IN VOUT G N D /AD J 3 VOUT 2 SOT-223 Top View 2 1 GND/ADJ 1 ORDERING INFORMATION Package Type TO-252 CM1117DCN252 CM1117KCN252 CM1117SCN252 CM1117CN252 CM1117GDCN252* CM1117GKCN252* CM1117GSCN252* CM1117GCN252* SOT-223 CM1117DCM223 CM1117KCM223 CM1117SCM223 CM1117CM223 CM1117GDCM223* CM1117GKCM223* CM1117GSCM223* CM1117GCM223* Operating Temperature Range (TA) 0℃ ~ +70℃ 0℃ ~ +70℃ 0℃ ~ +70℃ 0℃ ~ +70℃ 0℃ ~ +70℃ 0℃ ~ +70℃ 0℃ ~ +70℃ 0℃ ~ +70℃ Output Voltage 1.8V 2.5V 3.3V ADJ. 1.8V 2.5V 3.3V ADJ. *Note: G : Suffix for Pb Free Product 2004/06/01 Preliminary Rev. 1.5 Champion Microelectronic Corporation VIN 3 Page 1 CM1117 1A LOW DROPOUT VOLTAGE REGULATOR ABSOLUTE MAXIMUM RATINGS Input Voltage …………….…………………………………………….……. +12V Operating Junction Temperature Range, TJ ……………...… 0℃ to +125℃ Storage Temperature ………………………………….….…... -65℃ to +150℃ Lead Temperature (10 sec.) ……..……………………..….…………….... 260℃ RESOMMENDED OPERATING CONDITIONS Parameter Input Voltage Symbol VIN Min. 2.7 Typ.
