MD7028 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 | VOUT | output | Detector output, N-channel open drain (normally open, active low) for the MD70XX version, sinking up to a 10mA absolute maximum output current. |
| 2 | VDD | power_in | Positive supply input and monitored voltage, operating range up to 15V with an absolute maximum of 18V. |
| 3 | GND | power_in | Ground (VSS) reference pin for the supply and detector. |
