SPX1117M3-L-3-3/TR

SPX1117M3-L-3-3/TR is the tape-and-reel SOT-223-3 ordering code for the MaxLinear SPX1117 3.3 V low-dropout regulator, written word-for-word in the ordering information of the current MaxLinear SPX1117 datasheet (Rev 2.2.0, June 2025). MaxLinear publishes no lifecycle status field for this part; what can be stated from the maker’s own site is that the SPX1117 product page remains live and the datasheet was revised in June 2025 with this exact code in its ordering table, and no discontinuation notice accompanies either. It holds the 3.3 V output between 3.267 V and 3.333 V at 25 °C, widening to 3.234 V to 3.366 V across the 5 mA to 800 mA load range, with a dropout of 1.10 V typical and 1.30 V maximum at 800 mA, a current limit of 1.0 A minimum, 1.5 A typical and 2.0 A maximum, and a quiescent current of 5 mA typical and 10 mA maximum, over -40 °C to +125 °C junction. The selection point is the 1117-class socket in a SOT-223 tab package: a documented 800 mA rail for legacy and industrial boards where the footprint is already laid out. Selection advice: dropout on this class is over a volt at full load, so confirm the input rail keeps at least 1.3 V of headroom at the worst-case load and temperature before treating a 5 V input as sufficient. Parameters verified against the MaxLinear SPX1117 datasheet Rev 2.2.0 (ordering information and electrical characteristics).
