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. Absolute maximum -0.3 V to +45.0 V; recommended operating range 4.0 V to 42 V (start-up 3.0 V min at IOUT = 0 mA). Bypass to GND with CIN ≥ 0.1 µF located close to the pin. |+| 2 | N.C. | unconnected | Not Connected internally. May be left open, but ROHM recommends shorting to GND on the PCB for best practice. |+| 3 | VOUT | power_out | Regulated 3.3 V (Typ., ±2 %) output pin. Delivers up to 500 mA. Requires COUT ≥ 10 µF (Typ., ≥ 6 µF over temp/DC-bias) between VOUT and GND for stable operation; ceramic (X5R/X7R), tantalum, or electrolytic accepted. Absolute max VOUT range -0.3 V to +8.0 V. |+| 4 | GND | power_in | Ground / exposed thermal tab (FIN) on the back of the TO-252-3 package. Also serves as the primary heat-sinking path - solder to a copper pour for improved θJA. Keep at the lowest system potential under all operating conditions. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ROHM |+| Package | TO-252 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `BD433M5FP-CE2`+- `BD433M5FP-CE2BD433M5FP2-CZE2`+- `BD433M5FP-CE2BD433M5WFPJ-CZE2`+- `BD433M5FP-CE2BD433M5WFP2-CZE2`++## CAD (KiCad official)++- Symbol: `BD433M5FP-CE2`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [ROHM datasheet](docs/bd433m5fp-ce2-datasheet.pdf) (None pp, sha256 `36010bae6b7825a0`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
