**Diodes Incorporated** · Monitors & Reset Circuits · SOT-25

APX803L-27W5-7 from Diodes Incorporated, in a SOT-25. 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 | RESET | output | Active-low open-drain reset output; RESET voltage is limited to -0.3 V to 6.0 V and output current to 20 mA, with VOL at most 0.4 V at 3.5 mA sink when VCC = VTH - 0.2 V. |
| 2 | VCC | power_in | Operating voltage input with a recommended supply range of 0.9 V to 5.5 V and an absolute maximum rating of -0.3 V to 6.0 V. |
| 3 | GND | power_in | Ground reference pin. |
| 4 | NC | unconnected | No connection. |
| 5 | NC | unconnected | No connection. |

## CAD (land: KiCad; 3D: generated from the datasheet)

- Symbol: `APX803L-27W5-7`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-25, generated on the KiCad land (body 1.6 x 2.8 mm, terminals on the pads, 1.1 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)
- 3D model files: `apx803l-27w5-7-etched.step` / `apx803l-27w5-7-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `apx803l-27w5-7.step` / `apx803l-27w5-7.glb` are the bare package body.
