1 / 30 page LM1117-N www.ti.com SNOS412L – MAY 2004 – REVISED JULY 2012 LM1117/LM1117I 800mA Low-Dropout Linear Regulator Check for Samples: LM1117-N 1 FEATURES APPLICATIONS 2 • Available in 1.8V, 2.5V, 2.85V, 3.3V, 5V, and • 2.85V Model for SCSI-2 Active Termination Adjustable Versions • Post Regulator for Switching DC/DC Converter • Space Saving SOT-223 and LLP Packages • High Efficiency Linear Regulators • Current Limiting and Thermal Protection • Battery Charger • Output Current 800mA • Battery Powered Instrumentation • Line Regulation 0.2% (Max) • Load Regulation 0.4% (Max) • Temperature Range – LM1117: 0°C to 125°C – LM1117I: −40°C to 125°C DESCRIPTION The LM1117 is a series of low dropout voltage regulators with a dropout of 1.2V at 800mA of load current. It has the same pin-out as National Semiconductor's industry standard LM317. The LM1117 is available in an adjustable version, which can set the output voltage from 1.25V to 13.8V with only two external resistors. In addition, it is also available in five fixed voltages, 1.8V, 2.5V, 2.85V, 3.3V, and 5V. The LM1117 offers current limiting and thermal shutdown. Its circuit includes a zener trimmed bandgap reference to assure output voltage accuracy to within ±1%. The LM1117 series is available in LLP, TO-263, SOT-223, TO-220, and TO-252 D-PAK packages. A minimum of 10µF tantalum capacitor is required at the output to improve the transient response and stability. TYPICAL APPLICATION Active Terminator for SCSI-2 Bus Figure 1.
