EC48117

Data Sheet 1A LOW DROPOUT LINEAR REGULATOR General Description The EC48117 is aseries of low dropout three-terminal regulators with a dropout of 1.15V at 1A output current. The EC48117 series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandgap www.DataSheet4U.com reference to assure output voltage accuracy to be within 1%. Current limit is trimmed to ensure specified output current and controlled short-circuit current. Onchip thermal shutdown provides protection against any combination of overload and ambient temperature that would create excessive junction temperature. The EC48117 has an adjustable version that can provide the output voltage from 1.25V to 12V with only 2 external resistors. The EC48117 series is available in the industry standard SOT-223, SOT-89, TO-220, TO-252,TO-263 power packages. EC48117 Features Low Dropout Voltage: 1.15V at 1A Output Current Trimmed Current Limit On-Chip Thermal Shutdown Three-Terminal Adjustable or Fixed 1.5V, 1.8V, 2.5V, 3.3V, 5V Operation Junction Temperature: 0oC to 125oC Applications PC Motherboard LCD Monitor Graphic Card DVD-Video Player NIC/Switch Telecom Equipment ADSL Modem Printer and other Peripheral Equipment SOT-223 SOT-89 TO-220 TO-252 TO-263 Figure 1.
