MG6228T3B-18 from Megain, in a SOT-23-3. 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 | GND | power_in | Ground pin of the regulator (接地端), with the SOT23-3 pin table showing it as pin 1 in top view. |
| 2 | VOUT | power_out | Regulated output voltage pin; the output is 1.8 V to 5 V as set by the part's XX suffix, with up to 500 mA output current and ±2% output accuracy. |
| 3 | VIN | power_in | Input voltage pin; recommended VIN is 2.5 V to 6 V, and the absolute maximum rating is -0.3 V to +6.5 V. |
