AP2205-33W5-7 from Diodes Incorporated, in a SOT-25. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Input voltage, 2.3V to 24V recommended operating range (36V absolute maximum). |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable input; logic high is 2.0V minimum and logic low is 0.4V maximum (36V absolute maximum). |
| 4 | ADJ/NC | unconnected | Adjust output for the ADJ version; not connected for the fixed version (AP2205-33 is a fixed 3.3V part, so leave it not connected). |
| 5 | VOUT | power_out | Regulated output voltage, 3.3V fixed for this part, up to 200mA output current. |
