AP7387Q-33Y-13 from Diodes Incorporated, in a SOT-89-3. 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 | VOUT | power_out | Regulated output voltage of the LDO, which is specified for fixed 3.0V to 5V output versions and up to 150mA output current. |
| 2 | GND | power_in | Ground reference pin that should be connected to the external circuit ground to reduce voltage drop from trace impedance. |
| 3 | VIN | power_in | Input voltage pin with a recommended supply range of 5V to 60V and an absolute maximum rating of 80V. |
