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 | Device ground return. Reference for VDD, VOUT and the CE input threshold. Tie to the system ground plane with a low-impedance connection. |+| 2 | VOUT | power_out | Regulated output pin, fixed 2.5V nominal (±2% accuracy for the 'B' grade). Sources up to 1A load current; requires a 2.2uF output capacitor to ground for stability. Auto-discharged (~50Ω) when the regulator is disabled. |+| 3 | VDD | power_in | Unregulated input supply, 2.5V to 6.0V (absolute max 7V). Decouple with a 2.2uF (10uF recommended) ceramic capacitor to GND close to the pin. Chip Enable (CE) is tied to VDD internally through the application, since this 3-pin SOT-223-3 variant does not expose the CE pin (device is always enabled). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `BL9110-250BPFBFA`+- `BL9110-250BPFB`+- `BL9110-250BPFBFC`+- `BL9110-250BPFBFD`+- `BL9110-250BPFBDA`+- `BL9110-250BPFBAA`+- `BL9110-250BPFBBA`+- `BL9110-250BPFBBB`+- `BL9110-250BPFBCA`+- `BL9110-250BPFBEA`+- `BL9110-250BPFBEB`+- `BL9110-250BPFBGA`+- `BL9110-250BPFBGB`+- `BL9110-250BPFBGC`+- `BL9110-250BPFBHA`+- `BL9110-250BPFBIA`+- `BL9110-250BPFBIB`+- `BL9110-250BPFBIC`+- `BL9110-250BPFBJA`++## CAD (KiCad official)++- Symbol: `BL9110-250BPFB`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [BL Shanghai Belling datasheet](docs/bl9110-250bpfb-datasheet.pdf) (30 pp, sha256 `b94966cd4c52e86b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
