MD7536 from Shanghai Mingda Microelectronics, in a SOT-89-3. 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 terminal of the regulator. |
| 2 | VDD | power_in | Power supply input terminal; the absolute maximum input voltage is 18V and the regulator keeps the output in regulation up to 18V. |
| 3 | VOUT | power_out | Regulated output terminal; the datasheet requires VOUT not to exceed VIN+0.3V to avoid reverse current damage through the parasitic diode. |
