AP7383-50WR-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 | GND | power_in | Ground. |
| 2 | VIN | power_in | Input voltage, recommended operating range 3.5V to 30V (absolute maximum 33V). |
| 3 | VOUT | power_out | Regulated output voltage (5.0V fixed for the -50 version), up to 150mA with current limit of at least 150mA. |
| 4 | NC | unconnected | Not connected internally; connection to GND is recommended to maximize PCB copper for thermal dissipation. |
| 5 | NC | unconnected | Not connected internally; connection to GND is recommended to maximize PCB copper for thermal dissipation. |
