APX803L40-27SR-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 that asserts when VCC falls below the threshold, with output voltage rated -0.3 to 6.0V and 450ms typical reset timeout for the APX803L40 option. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | VCC | power_in | Operating voltage input monitored by the detector, with a recommended supply range of 0.9 to 5.5V and an absolute maximum of -0.3 to 6.0V. |
