Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | RESET | output | Active-low, open-drain reset output. Asserts low when VCC falls below the reset threshold (3.08V typ. for -31) and remains low for the reset timeout (240ms typ.) after VCC returns above the threshold. Rated to sink up to 20mA; guaranteed valid low for VCC > 1V. Requires an external pull-up resistor to the desired logic rail. |+| 2 | GND | power_in | Device ground reference. |+| 3 | VCC | power_in | Operating supply voltage input and monitored rail. Recommended operating range 1.0V to 5.5V; absolute max 6.0V. Typical supply current 10µA. Reset is asserted whenever VCC falls below the preset threshold (3.08V typ. for the -31 option). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `APX803S-31SR-7`+- `APX803S-31SR-7SA-7`++## CAD (KiCad official)++- Symbol: `APX803S-31SR-7`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](docs/apx803s-31sr-7-datasheet.pdf) (9 pp, sha256 `58d0867f60d9b289`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
