**MICRONE** · Monitors & Reset Circuits · SOT-23

ME2807A22M3G from MICRONE, in a SOT-23. 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 | CMOS output voltage that goes low when VIN falls below the detection voltage (VDET = 2.2V for this part), with absolute maximum output current of 20 mA. |
| 2 | GND | power_in | Ground. |
| 3 | VIN | power_in | Input voltage and supply pin, operating range 0.7V to 18V (absolute maximum 18V), monitored against the detection voltage. |
