BL9161G-30BARN from BL Shanghai Belling, in a SOT-23-5. 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. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 625 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
