The 10-WSON package (3x3 mm) with exposed pad helps pull heat into the PCB ground plane. Operating temperature range is -30°C to 85°C, so it's suited for commercial and some industrial environments, but not for under-hood automotive or extended outdoor exposure without derating.
If you're sourcing it through independent distribution, we can quote sealed reels with consistent date-codes — no mixed-date auction lots.
There is no pin-compatible direct replacement listed. The LM2750LD-ADJ/NOPB is a charge-pump part but it's a step-up (boost) with adjustable output, not a step-down fixed 1.5V. For a step-down charge pump at 1.5V, the LM2771SD/NOPB is the specific part. If you need a higher current or adjustable output, consider a buck converter like the LMS3655 or LM53625, but those are different topologies and packages.
