AP7366-18W5-7 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 | IN | power_in | Voltage input pin (2.2V to 6V recommended); bypass to ground through at least a 1µF MLCC capacitor. |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Active-high enable input; logic low ≤0.3V turns the output off, logic high ≥1.0V turns it on, and it should be tied to IN if unused. |
| 4 | NC | unconnected | No connection. |
| 5 | OUT | power_out | Voltage output pin (fixed 1.8V for this part, up to 600mA); bypass to ground through a 1µF MLCC capacitor. |
