AP2205-50W5-7 from Diodes Incorporated, 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 | Unregulated supply input, 2.3V to 24V (absolute max 36V). Bypass to GND with a 1.0µF ceramic capacitor placed close to the pin. |
| 2 | GND | power_in | Device ground return. Typical ground current is 36µA at IOUT=100µA, rising to 2.5mA at IOUT=150mA. |
| 3 | EN | input | Enable input. VIH ≥ 2.0V turns the regulator on; VIL ≤ 0.4V forces the device into shutdown (standby current 0.01µA typ). EN input current 3µA typ; absolute max 36V. |
| 4 | NC | unconnected | Not connected on the fixed-voltage version (AP2205-50W5-7 is the 5.0V fixed variant). On the ADJ (adjustable) version this pin is ADJ, the feedback input tied to a resistor divider from VOUT (VREF=1.24V). Leave floating or tie to GND. |
| 5 | VOUT | power_out | Regulated 5.0V output, up to 200mA (VOUT>1.8V). Requires a 2.2µF ceramic output capacitor for stability. Dropout is 320mV typ at IOUT=100mA. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 554 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.
