WL2836D33-4 from WILLSEMI(Will Semicon), in a DFN1x1-4L. 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, which for WL2836D33-4 is 3.3V within the stated 0.9V~3.3V output range. |
| 2 | GND | power_in | Ground reference pin; the datasheet states that the exposed pad EP at GND level must also connect to GND. |
| 3 | EN | input | Active-high enable; the datasheet gives EN logic high at 1V minimum and EN logic low at 0.4V maximum. |
| 4 | VIN | power_in | Input supply pin with an operating input voltage range of 1.4V to 5.5V. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
