AP2204K-2.5TRG1 from Diodes Incorporated, in a SOT-23-5. 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 pin; recommended operating range is 2.6V (or VOUT+1V if larger) to 24V. |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable input; logic high is at least 2.0V and logic low is at most 0.4V. |
| 4 | ADJ/NC | unconnected | Adjust pin for the ADJ version; on the fixed version (such as -2.5) it is not connected internally, and connecting it to GND is recommended to maximize PCB copper for thermal dissipation. |
| 5 | VOUT | power_out | Regulated output voltage, up to 150mA output current. |
