**Shanghai Mingda Microelectronics** · Supervisor And Reset ICs · SOT-23-3L

MD7025C from Shanghai Mingda Microelectronics, in a SOT-23-3L. 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 (CMOS, normally high, active low for the MD7025C), swinging between VSS-0.3V and VDD+0.3V with 10mA maximum output current. |
| 2 | GND | power_in | Ground (VSS) reference for the detector and output. |
| 3 | VDD | power_in | Supply input and monitored voltage, with 1.5V to 15V operating range for MD7025 and -0.3V to 18V absolute maximum. |
