The Texas Instruments LM1117IMPX-ADJ/NOPB is an 800 mA low-dropout regulator with an adjustable output from 1.25 V to 13.8 V, set by two external resistors, in the industrial SOT-223 package. Its 1.2 V maximum dropout, ±1% reference accuracy and integrated current-limit and thermal-shutdown protection make it a flexible building block for custom voltage rails in industrial designs, supplied on tape and reel.
