MD7070 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 | N-channel open-drain detector output (normally open, active low) that pulls low when VDD falls below the 7.0V detect threshold, with 5mA min sink current at VOUT=0.2V; output voltage range is VSS-0.3V to VDD+0.3V and max output current is 10mA. |
| 2 | VDD | power_in | Positive supply and voltage-sense input; MD7070 operating voltage is 1.0V to 15V with 18V absolute maximum, detect voltage 7.0V (6.790V to 7.210V) with 0.35V typical hysteresis. |
| 3 | GND | power_in | Ground (VSS) reference for the supply and the output. |
