The Texas Instruments LM1117MPX-5.0/NOPB is an 800 mA low-dropout linear regulator delivering a fixed 5.0 V output in the SOT-223 package, supplied on tape and reel. With ±1% output accuracy and 1.2 V maximum dropout, it is a compact solution for 5 V rails in volume production, protected by on-chip current limiting and thermal shutdown.
