Part Details:

LM1 April 2006 117/LM1 LM1117/LM1117I 1 800mA Low-Dropout Linear Regulator 17I General Description Features 800mA The LM1117 is a series of low dropout voltage regulators n Available in 1.8V, 2.5V, 2.85V, 3.3V, 5V, and Adjustable with a dropout of 1.2V at 800mA of load current. It has the Versions same pin-out as National Semiconductor s industry standard n Space Saving SOT-223 and LLP Packages LM317. n Current Limiting and Thermal Protection The LM1117 is available in an adjustable version, which can n Output Current 800mA Low-Dropout set the output voltage from 1.25V to 13.8V with only two n Line Regulation 0.2% (Max) external resistors. In addition, it is also available in five fixed n Load Regulation 0.4% (Max) voltages, 1.8V, 2.5V, 2.85V, 3.3V, and 5V. n Temperature Range The LM1117 offers current limiting and thermal shutdown. Its -- LM1117 0°C to 125°C circuit includes a zener trimmed bandgap reference to as- -- LM1117I -40°C to 125°C sure output voltage accuracy to within ±1%. The LM1117 series is available in LLP, TO-263, SOT-223, Applications TO-220, and TO-252 D-PAK packages. A minimum of 10µF n 2.85V Model for SCSI-2 Active Termination tantalum capacitor is required at the output to improve the Linear n Post Regulator for Switching DC/DC Converter transient response and stability. n High Efficiency Linear Regulators n Battery Charger n Battery Powered Instrumentation Regulator Typical Application Active Terminator for SCSI-2 Bus 10091905 Fixed Output Regulator 10091928 © 2006 National Semiconductor Corporation
