MIC29302WU

MIC29302WU is a UMW 3 A adjustable low-dropout linear regulator in a TO-263-5 package, setting its output from a 1.24 V reference with a divider, with typical dropout of 450 mV at full load — a high-current point-of-load rail for processor, FPGA and legacy 3.3 V / 5 V systems. UMW's own manual, whose ordering information carries this exact code, rates the input at 16 V maximum — read that figure from the UMW manual alone. The same MIC29302WU code is also documented by Microchip with a 26 V input figure — the two makers' parts share name and package but not a datasheet, and applying the 26 V rating to the UMW device would overstress it. Selection advice: qualify and buy this code as a UMW part, with the UMW manual as the governing document; if your design needs the higher input rating, that is a different sourcing decision, not a substitution. The TO-263 tab is the heatsink path — at 3 A the dissipation is set by input-output differential, so compute it before committing the layout. Parameters verified against UMW documentation.
