**SGMICRO** · Supervisor And Reset ICs · SOT-23

SGM803-RXN3L from SGMICRO, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground Pin. |
| 2 | RESET̄ | output | Active-Low Reset Output that goes low when VCC is lower than the reset threshold and remains low for 240ms (TYP) after VCC exceeds the threshold. |
| 3 | VCC | power_in | Supply Voltage Pin. |
