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 | GND | power_in | Ground reference for the regulator. Connect to system ground plane. |+| 2 | OUT | power_out | Regulated output pin. Provides 3.3V (typ, LP3986-33 variant) at up to 300mA. Requires a 2.2µF (or 1µF X7R) low-ESR ceramic capacitor to GND for stability. |+| 3 | VIN | power_in | Power supply input. Operating range 2.5V to 6V (absolute maximum 7V). Requires a 2.2µF ceramic input capacitor to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | LOWPOWER |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `LP3986-33B3F33B3F`+- `LP3986-33B3F33X3F`++## CAD (KiCad official)++- Symbol: `LP3986-33B3F`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [LOWPOWER datasheet](docs/lp3986-33b3f-datasheet.pdf) (9 pp, sha256 `0ed045971cf1375c`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
