BD433M2FP3-CE2

ROHM · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-3

BD433M2FP3-CE2 from ROHM, in a SOT-223-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC power_in Supply voltage input pin. Operating range 3.0 V to 42 V; absolute maximum 45 V. Bypass with ≥0.1 µF CIN close to the pin.
2 GND power_in Ground pin. Common return for input and output. Tie together with pin 4 (FIN exposed tab) at the ground plane.
3 VOUT power_out Regulated 3.3 V output pin, up to 200 mA. Requires ≥10 µF COUT (electrolytic, tantalum or ceramic) for phase compensation. Output accuracy ±2 %.
4 GND power_in FIN - exposed thermal tab / heat-sink fin, internally connected to GND. Must be soldered to the PCB ground copper for heat dissipation (Pd = 0.60 W in SOT223-4F).

  • 3D model files: bd433m2fp3-ce2-etched.step / bd433m2fp3-ce2-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bd433m2fp3-ce2.step / bd433m2fp3-ce2.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
bd433m2fp3-ce2.step 64 KB You want the bare part, or you mark your own boards.
bd433m2fp3-ce2-etched.step 2.6 MB You want the part with BD433M2FP3-CE2 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 624 faces against 75 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
