Fixed-output LDO regulator — design-fit note
The UPC29M07HB-AZ is a fixed-output linear regulator from Renesas Electronics, classified under Power Management (PMIC / Gate Driver). As a fixed LDO, the output voltage is preset internally — no external resistor divider is needed, which saves two components and one feedback-node noise path on the PCB. The part ships in Bulk packaging, meaning it arrives in tubes or trays rather than tape-and-reel. This is typical for low-to-medium volume builds or prototype runs; for high-volume pick-and-place, confirm the reel option or plan a tube-to-reel transfer.
Lifecycle and compliance
RoHS3 compliance (2011/65/EU + 2015/863) is confirmed, so the part meets the latest EU restriction on hazardous substances.
Sourcing posture
This is an active, in-production part — no allocation signal, no LTB window.
