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). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ROHM |+| Package | SOT-223-3 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `BD433M2FP3-CE2`+- `BD433M2FP3-CE2WFP3-CE2`+- `BD433M2FP3-CE2EFJ-CE2`+- `BD433M2FP3-CE2WEFJ-CE2`++## CAD (KiCad official)++- Symbol: `BD433M2FP3-CE2`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [ROHM datasheet](docs/bd433m2fp3-ce2-datasheet.pdf) (37 pp, sha256 `0bd95b7b4b1378f8`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
