Texas Instruments LM1117 SOT-223 Adjustable Voltage Regulator 800mA

The Texas Instruments LM1117 is a high-performance, low-dropout voltage regulator designed for applications requiring stable and accurate power supply. With a low dropout voltage of just 1.2V at its full 800mA output current, it efficiently regulates voltage even when the input supply is only slightly higher than the desired output, making it ideal for battery-powered and energy-sensitive circuits.

This regulator is available in an adjustable version, allowing the output voltage to be precisely set from 1.25V to 13.8V using only two external resistors. This flexibility makes it suitable for a vast range of digital and analogue circuits requiring custom voltage levels. It features the same pin-out as the industry-standard LM317, ensuring easy drop-in replacement and simplified PCB design.
