LM1117

800 mA Low-Dropout Linear Regulator LM1117, LM1117I The LM1117 is a low dropout voltage regulator with a dropout of 1.2 V at 800 mA of load current. The LM1117 is available in an adjustable version, which can set the output voltage from 1.25 to 13.8 V with only two external resistors. In addition, it is available in five fixed voltages, 1.8 V, 2.5 V, 3.3 V, and 5 V. The LM1117 offers current limiting and thermal shutdown. Its circuit is trimmed to assure output voltage accuracy to within +/−1%. Features Available in 1.8 V, 2.5 V, 3.3 V, 5.0 V, and Adjustable Versions Space−Saving SOT−223 Package Current Limiting and Thermal Protection Output Current 800 mA Line Regulation 0.2% (Maximum) Load Regulation 0.4% (Maximum) Temperature Range: −40°C to 125°C These are Pb-Free Devices Applications Post Regulator for Switching DC−DC Converter High Efficiency Linear Regulators Battery Chargers Portable Instrumentation Active SCSI Termination Regulation www.onsemi.com SOT−223 CASE 318H PIN CONFIGURATION Tab 123 SOT−223 (Top View) Pin: 1.
