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 | VIN | power_in | Power input voltage. Operating range 2.2V to 6V (absolute max +6V). Requires 1µF input capacitor (CIN) for stability. |+| 2 | GND | power_in | Ground reference for the regulator. |+| 3 | EN | input | Chip enable pin (active high) with internal pull-down resistor. VIH ≥ 1.2V starts the regulator; VIL ≤ 0.4V forces shutdown (ISTBY ≈ 0.01µA typical). Absolute max -0.3V to VIN. |+| 4 | NC | unconnected | No internal connection. May be left floating or tied to any potential. |+| 5 | VOUT | power_out | Regulated output voltage (3.0V for the -30 option, ±2% accuracy with B suffix). Delivers up to 300mA. Requires only 1µF output capacitor for stability; ≥2.2µF is recommended for 1.2V/1.5V/1.8V variants. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `BL9161G-30BARN`+- `BL9161G-30BARNURN`+- `BL9161G-30BARNRT`+- `BL9161G-30BARNDRN`++## CAD (KiCad official)++- Symbol: `BL9161G-30BARN`+- 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/bl9161g-30barn-datasheet.pdf) (12 pp, sha256 `74f47540de0b9365`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
