MD7672E50UB2 from Shanghai Mingda Microelectronics, in a TO-252-4L. 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 | EN | input | Enable pin: minimum 1.6V enables the device and maximum 0.4V shuts it down. |
| 2 | VIN | power_in | Power input pin, operating range 2 to 6V, to be closely decoupled to GND with a 4.7µF or greater ceramic capacitor. |
| 3 | GND | power_in | Ground signal pin. |
| 4 | VOUT | power_out | Regulator output pin delivering up to 2A, with a 4.7µF or larger ceramic output capacitor recommended. |
| 5 | ADJ | input | Adjustable pin: set the output voltage with an external resistor divider (reference 0.7V nominal), or connect to GND for the internally set VOUT = 5V. |
