LM1117MPX-3.3/NOPB

LM1117MPX-3.3/NOPB is the tape-and-reel SOT-223 ordering code for the Texas Instruments LM1117 fixed 3.3 V linear regulator, listed as Active on the TI part-details page for this exact code. The /NOPB suffix is part of the status story: distributor listings that mark an LM1117MPX-3.3 as obsolete refer to the variant without /NOPB, which is a different ordering code and does not describe this one. It delivers 3.3 V within ±1% at up to 800 mA, with a dropout voltage of 1.2 V at an 800 mA load, line regulation of 0.2% maximum, load regulation of 0.4% maximum and an input ceiling of 15 V, over a 0 °C to +125 °C range - the MP code is the commercial temperature grade, not the -40 °C industrial grade. The selection point is the long-running 1117 footprint in SOT-223 for cost-sensitive 3.3 V rails in consumer and industrial boards. Selection advice: plan the input headroom and the SOT-223 thermal path around the 1.2 V dropout at full load, and do not read the commercial temperature range as industrial when qualifying for outdoor or cabinet installations. Parameters verified against the TI LM1117 datasheet SNOSB13 and the part-details page for this ordering code.
