MIC5225-3.3YM5-TR

MIC5225-3.3YM5-TR is the tape-and-reel code for the Microchip MIC5225 fixed 3.3 V low-dropout regulator in SOT-23-5 (base code MIC5225-3.3YM5, part marking QT33): 150 mA output with a maximum dropout of 0.45 V at full load, input up to 16 V, an enable pin for rail sequencing, and a -40 °C to +125 °C junction range. The µCap design stays stable with small ceramic output capacitors, so a quiet 3.3 V rail for sensors, RTC domains and RF front ends costs one SOT-23-5 and one capacitor instead of a larger regulator footprint. The code appeared in an ic.net.cn buy request for 1,688 pieces on scan day, evidence of live demand. Selection advice: the -TR suffix is only the reel form of the same YM5 code — quote the full string so packing is not confused at goods-in; check dropout headroom at your worst-case input, since 0.45 V maximum at 150 mA is the binding limit on near-3.3 V inputs. Microchip keeps the family in production, with a 2024 datasheet revision and a 2025 family PCN on record. Parameters verified against Microchip documentation.
