MG6226D4-18 from Megain, in a DFN-4L(1x1). 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 pin, rated up to 300 mA, with output accuracy of ±2% over temperature. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Enable pin; the datasheet lists VENHI as 0.6 V and VENLO as 0.2 V. |
| 4 | VIN | power_in | Input voltage pin; recommended input range is 2.5 V to 5.5 V, with an absolute maximum of -0.3 V to +6.5 V. |
| 5 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
