AP62301WU-7 from Diodes Incorporated, in a TSOT-26. 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 | Power ground for the regulator (TSOT26 pin 1 per the pin description table on page 3). |
| 2 | SW | power_out | Power switching output node that supplies power to the output; the output LC filter connects from SW to the load. |
| 3 | VIN | power_in | Power input that supplies the IC and the step-down power MOSFETs; drive with a 4.2V to 18V source and bypass to GND with a suitably large capacitor. |
| 4 | FB | input | Feedback sensing terminal for the output voltage; connect to the output resistive divider (VOUT range 0.8V to 7V). |
| 5 | EN | input | Digital enable input: drive high to turn the regulator on and low to turn it off, with a 1.2V precision threshold for UVLO programming; leave floating for automatic startup. |
| 6 | BST | power_in | High-side gate drive boost input; a 100nF or higher capacitor from BST to SW is recommended to power the high-side driver. |
