MD7218D60UA2 from Shanghai Mingda Microelectronics, in a TO-252-2L. 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 | VIN | power_in | Input supply pin for the regulator, with an operating input voltage of 2.2V to 18V and an absolute maximum rating of -0.3V to 20V. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | VOUT | power_out | Regulated output pin delivering up to 1A, which must not be driven above VIN+0.3V to avoid reverse current damage through the internal parasitic diode. |
