APX803S-46SA-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 | GND | power_in | Ground reference pin for the supervisor. |
| 2 | RESET | output | Active-low open-drain reset output; RESET is guaranteed logic low for VCC > 1V, and the absolute maximum VRESET is -0.3 to 6 V with IO output current limited to 20 mA. |
| 3 | VCC | power_in | Operating supply voltage input, recommended 1.0 V to 5.5 V, with absolute maximum -0.3 to +6.0 V. |
