AP7361C-33ER-13 from Diodes Incorporated, in a SOT-223R. 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 | GND | power_in | Device ground and thermal reference. Also connected to the tab. |
| 2 | OUT | power_out | Regulated 3.3V output. Bypass to ground through at least a 2.2µF ceramic capacitor; larger COUT improves AC load response. Max continuous output current 1A; internal current limit ~1.5A typ; short-circuit current ~400mA. |
| 3 | IN | power_in | Regulator input supply, 2.2V to 6.0V recommended (absolute max 6.5V). Bypass to ground through at least a 1µF ceramic capacitor close to the pin. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 632 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.
