XC6220B331MR-G from Torex Semicon, in a SOT-25. 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. Operating range 1.6V-6.0V (absolute max VSS-0.3 to +6.5V). Bypass with a ceramic capacitor (typ. 1 µF) close to the pin. |
| 2 | VSS | power_in | Ground reference for the regulator. Common return for VIN, VOUT, and CE. |
| 3 | CE | input | Chip Enable (ON/OFF control). VCE ≤ 0.4V = OFF (stand-by), 1.2V ≤ VCE ≤ 6.0V = ON. Absolute max VSS-0.3 to +6.5V. Do not leave open on A/B series (undefined); C/D series has internal pull-down. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to VSS. |
| 5 | VOUT | power_out | Regulated output, factory-trimmed to 3.3V (0.8V-5.0V range in family). Output current up to 1000mA (limit ~1200mA typ). Requires a low-ESR ceramic output capacitor CL (typ. 1 µF; 22 µF for inrush spec). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 675 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.
