XL1509-5.0

XL1509-5.0 is the SOP-8 ordering code for the UMW (UTD Semiconductor) XL1509 fixed 5 V step-down converter, listed word-for-word as UMW XL1509-5.0 in the ordering information of the UMW datasheet (June 2025) at 2,500 pieces per reel. UMW publishes no lifecycle grading for the part; the code stands in the maker’s current datasheet ordering table. Its own electrical table - UMW’s figures, not those of any other vendor selling an XL1509-named part - holds the 5 V output between 4.8 V and 5.2 V across a 7 V to 40 V input and a 0.2 A to 2 A load, at 82 % typical efficiency, with an oscillator of 117 kHz minimum, 150 kHz typical and 183 kHz maximum, quiescent current of 2 mA typical and 10 mA maximum, and an overall input range of 4.5 V to 40 V. The selection point mirrors the fixed-output XL1509 concept: a 5 V logic rail from 12 V or 24 V with the feedback divider set internally. Selection advice: this SOP-8 UMW code is not interchangeable on paper with the XLSEMI XL1509-5.0E1 also listed in this catalog - the XLSEMI code carries its own datasheet figures, and UMW separately lists an XL1509E line in ESOP-8 at 3 A - so confirm the vendor, the package body and the electrical table together before substituting any XL1509-named offer. Parameters verified against the UMW XL1509 datasheet (ordering information and electrical characteristics, June 2025).
