APX803-31SRG-7 from Diodes Incorporated, 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 | RESET | output | Active-low open-drain reset output, guaranteed logic low for VCC > 1V and held low for at least 140ms after VCC rises above the reset threshold; absolute maximum -0.3 to 6V. |
| 2 | GND | power_in | Ground. |
| 3 | VCC | power_in | Operating voltage input, recommended 1.1V to 5.5V (absolute maximum -0.3 to +6.0V). |
