SHENZHEN YANGJING MICROELECTRONICS CO.,LTD 1A LOW DROPOUT LINEAR REGULATOR GENERAL DESCRIPTION The 1117 is a series of low dropout three-terminal egulators with a dropout of 1.15V at 1A output current. The 1117 series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within 1%. Current limit is trimmed to ensure specified output Current and controlled short-circuit current. On-chip thermal shutdown provides protection against any combination of overload and ambient temperature that would create excessive junction temperature. The 1117 has an adjustable version, that can provide the output voltage from 1.25V to 5V with only 2 external resistors. The 1117 series is available in the industry standard SOT-223,SOT-89,TO-220,TO-252 and TO-263 power packages. 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: 0 ℃ to125℃ APPLICATIONS • PC Motherboard • LCD Monitor • Graphic Card • DVD-Video player • NIC/Switch • Telecom Modem • ADSL Modem • Printer and other peripheral Equipment YANGJING MICROELECTRONICS www.szyangjing.com 4007-888-606 2 PIN CONFIGURATIONS T Package (SOT-223) A Package (SOT-89) P Package (TO-220) U Package (TO-252) B Package (TO-263) ADJ/GND OUTPUT INPUT Figure 2.
