Product details

Fixed 3.3 V rail for noise-sensitive loads

The BD3570YHFP-MTR is a single-output positive LDO regulator from ROHM, delivering a fixed 3.3 V at up to 500 mA. Quiescent current is 50 µA typical, so the regulator's own draw doesn't dominate the budget in always-on or battery-backed sections of the board.

Temperature grade and protection set

The 0.48 V dropout at 200 mA means a 3.5 V input keeps 3.3 V regulation at moderate loads.

Supplied in a TO-263-6 (D²Pak) with 5 leads plus the exposed tab (HRP-5). The tab is the main thermal path — a copper pour on the PCB's top layer under the tab, with vias to an inner ground plane, pulls heat away from the die. Surface-mount assembly; the tape-and-reel option suits volume pick-and-place.

ROHS3 compliant, so it passes the material declaration for EU and most global markets without an exemption.

Frequently asked questions
