AP7361C-33E-13 from Diodes Incorporated, in a SOT-223. 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 | IN | power_in | Regulator input supply, 2.2V to 6.0V. Bypass to ground with at least a 1µF (typ. 4.7µF) ceramic capacitor placed close to the pin. Absolute maximum 6.5V. |
| 2 | GND | power_in | Device ground reference. The SOT-223 tab (pin 2) also serves as the primary thermal path; connect to a copper plane sized to meet the ~1100mW package dissipation budget. |
| 3 | OUT | power_out | Regulated 3.3V output, up to 1A. Bypass to ground with at least a 2.2µF (typ. 4.7µF) ceramic capacitor; a larger cap improves ac load response. Internal 100Ω discharge resistor pulls OUT down when disabled/unpowered. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 582 faces against 75 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.
