LM1117/LM1117I  
800mA Low-Dropout Linear Regulator  
General Description  
Features  
n Available in 1.8V, 2.5V, 2.85V, 3.3V, 5V, and Adjustable  
Versions  
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.  
n Space Saving SOT-223 and LLP Packages  
n Current Limiting and Thermal Protection  
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.

0.2% (Max)  
0.4% (Max)  
The LM1117 offers current limiting and thermal shutdown. Its  
circuit includes a zener trimmed bandgap reference to as-  
sure output voltage accuracy to within 1%.  
0˚C to 125˚C  
−40˚C to 125˚C  
— LM1117I  
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.  
Applications  
n 2.85V Model for SCSI-2 Active Termination  
n Post Regulator for Switching DC/DC Converter  
n High Efficiency Linear Regulators  
n Battery Charger  
n Battery Powered Instrumentation  
Typical Application  
Active Terminator for SCSI-2 Bus
