LM1117 Description

Short technical summary and product information.

The Texas Instruments LM1117 is a versatile low-dropout linear voltage regulator designed for applications requiring up to 800mA of output current. It features a low dropout voltage of 1.2V at 800mA, making it efficient for battery-powered devices.

 

The LM1117 is offered in both adjustable and fixed output voltage versions. The adjustable version can be set from 1.25V to 13.8V using two external resistors. Fixed voltage options include 1.8V, 2.5V, 3.3V, and 5V. The regulator includes built-in current limiting and thermal shutdown protection for enhanced reliability.

 

Key electrical specifications include a maximum input voltage of 15V, line regulation of 0.2% (maximum), and load regulation of 0.4% (maximum). A minimum output capacitance of 10µF is recommended for stability. The device operates over a temperature range of -40°C to 125°C for the LM1117I variant.

 

Available in space-saving packages such as SOT-223 and WSON, as well as TO-220 and TO-263, the LM1117 is suitable for portable instrumentation, battery chargers, and post-regulation for switching DC-DC converters.
