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 | Vss | power_in | Ground reference for the regulator. Connect to system ground. |+| 2 | Vout | power_out | Regulated output voltage (2.5V for BL8503-25PRM, factory-trimmed within +/-2%). Supplies up to 250mA. Requires a 1uF (tantalum recommended) output capacitor for loop stability. |+| 3 | Vin | power_in | Unregulated supply input. Operating range 1.5V-10V (recommended max 8V); requires at least Vout + dropout (~170mV @ 100mA, ~400mV @ 250mA). A 1uF (tantalum recommended) input capacitor is required. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOT-23-3L |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `BL8503-25PRM`+- `BL8503-25PRMPSM`+- `BL8503-25PRMPSA`+- `BL8503-25PRMPSB`+- `BL8503-25PRMPT`++## CAD (KiCad official)++- Symbol: `BL8503-25PRM`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [BL Shanghai Belling datasheet](docs/bl8503-25prm-datasheet.pdf) (13 pp, sha256 `8f6684221c2cf4c4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
