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 1.6V to 5.5V (absolute max 6V). Requires ≥1µF ceramic input capacitor (C1) close to the pin. |+| 2 | GND | power_in | Device ground reference for the regulator and reference. Connect to the system ground plane. |+| 3 | EN | input | Chip enable input with internal pull-down resistor. Active-high (VIH ≥ 1.2V enables regulator, VIL ≤ 0.4V forces shutdown, ~0.1µA standby). EN input range -0.3V to VIN. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to any convenient node; not internally bonded. |+| 5 | VOUT | power_out | Regulated output voltage (3.3V for the -330 option). Delivers up to 300mA; current-limit typ 350mA, short-circuit current typ 180mA. Requires only 1µF ceramic output capacitor (C2) for 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.++- `BL9162-330BARN`+- `BL9162-330BARNURN`+- `BL9162-330BARNDRN`++## CAD (KiCad official)++- Symbol: `BL9162-330BARN`+- 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/bl9162-330barn-datasheet.pdf) (14 pp, sha256 `8e3e5e0499cd6d76`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
