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 | VDD | power_in | Input supply pin. Accepts 1.8V to 8V (10V absolute max); a 1uF input capacitor is recommended for stability. |+| 2 | GND | power_in | Ground reference pin for the regulator. |+| 3 | CE | input | Chip enable input. Drive high (VceH >= 1.5V, up to Vin) to enable the regulator; drive low (VceL <= 0.25V) to place the part in 0.1uA standby. Internal pull-down resistance is 5MOhm (typ). |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to a convenient net. |+| 5 | VOUT | power_out | Regulated 3.0V output. Delivers up to 150mA with short-circuit protection at ~20mA (Vout=0V). A 1uF/2.2uF output capacitor is required for loop stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `BL8555-30PRA`+- `BL8555-30PRAPRB`+- `BL8555-30PRAPQ`++## CAD (KiCad official)++- Symbol: `BL8555-30PRA`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [BL Shanghai Belling datasheet](docs/bl8555-30pra-datasheet.pdf) (9 pp, sha256 `447ecc9000aa319a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
