LM1117MPX-ADJ/NOPB TI Linear Regulators

The LM1117MPX-ADJ/NOPB is an 800mA low-dropout linear regulator from Texas Instruments, available in a space-saving SOT-223 package. For selection, verify input voltage from 2.6V to 15V; confirm adjustable output voltage from 1.25V to 13.8V using two external resistors. Note typical dropout voltage of 1.2V at 800mA and ±1% output accuracy. Quiescent current is 5mA typical, with a maximum of 10mA. PSRR is 75dB at 120Hz. Ensure operating temperature from 0°C to 125°C; for -40°C to 125°C operation, select LM1117I version. A minimum 10µF tantalum capacitor is required at the output for stability. Features include current limiting and thermal shutdown protection. Ideal for post-regulation in switching power supplies, battery-powered devices, microcontroller power rails, industrial sensors, consumer electronics, automotive systems (with I-grade), and point-of-load regulation requiring stable, adjustable voltage output.
