APX810S05-31SA-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 and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference pin for the supervisor circuit. |
| 2 | RESET | output | Push-pull active-high reset output on the APX810S; it asserts when VCC falls below the reset threshold and stays asserted for at least 240 ms after VCC recovers, with a maximum output current of 20 mA. |
| 3 | VCC | power_in | Operating voltage input; recommended supply range is 1.0 V to 5.5 V, with an absolute maximum of -0.3 V to 6.0 V. |

CAD (land: KiCad; 3D: generated from the datasheet)
- Symbol:
APX810S05-31SA-7 - Footprint:
Package_TO_SOT_SMD:SOT-23 - 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.025 mm tall, datasheet A, nominal). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
