Description :

BM1117 GENERAL DESCRIPTION The BM1117 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 within 1% accuray. Current limit is also trimmed, minimizing the stress under overload conditions on both the regulator and power source circuitry. The BM1117 devices are pin compatible with other three-terminal SCSI regulators and are offered in the low profile surface mount SOT-223 package and in the TO-252 (DPAK) plastic package. FEATURES Three Terminal Adjustable or Fixed Voltages- 1.5V, 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. SOT-223 and TO-252 package available APPLICATIONS High Efficiency Linear Regulators Post Regulators for Switching Supplies  5V to 3.3V Linear Regulator  Power Management for Notebook  Battery Chargers  Battery Powered Instrumentation  Active SCSI Terminators ORDERING INFORMATION PACKAGE TYPE OPERATING JUNCTION TEMPERATURE RANGE 0 to 125° C 0 to 125° C 0 to 125° C 0 to 125° C 0 to 125° C 0 to 125° C 0 to 125° C TO-252 BM1117-ADJ BM1117-1.5 BM1117-1.8 BM1117-2.5 BM1117-2.85 BM1117-3.3 BM1117–5.0 SOT-223 BM1117-ADJ BM1117-1.5 BM1117-1.8 BM1117-2.5 BM1117-2.85 BM1117-3.3 BM1117-5.0 *For additional available fixed voltages contact factory.
