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 | VOUT | power_out | Regulated output voltage (5.0V for -50 suffix, ±2%). Requires a 1uF ceramic output capacitor to GND for stability. Maximum output current 150mA; internally current-limited at ~180mA. |+| 2 | GND | power_in | Device ground reference. Should be tied to the ground plane; also the thermal path for the SOT-89 tab (pin 2 is fused to the mounting tab). |+| 3 | VIN | power_in | Unregulated supply input, 3V to 40V (50V absolute max). Requires a 1uF ceramic input capacitor to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `BL8078CC3BTR50`+- `BL8078CC3BTR50CC3TR`++## CAD (KiCad official)++- Symbol: `BL8078CC3BTR50`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [BL Shanghai Belling datasheet](docs/bl8078cc3btr50-datasheet.pdf) (5 pp, sha256 `85f4bbd4c457d3ba`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
