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 | GND | power_in | Ground reference for the supervisor. |+| 2 | /RESET | output | Active-low, open-drain reset output. /RESET is pulled low while VCC is below the 2.93V reset threshold and remains low for 240ms (typ, min 150ms) after VCC rises above the threshold. Open-drain output requires an external pull-up resistor (sink capability 1.2mA at VOL = 0.3V; leakage 1µA max when de-asserted). Reset assertion is guaranteed down to VCC = 1V. |+| 3 | VCC | power_in | Power supply input that is also the monitored voltage. Operating range 1.2V to 5.5V (over -40°C to +125°C); absolute max 6V. Typical supply current 13µA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | SGMICRO |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `SGM803-SXN3L/TR`+- `SGM803-SXN3LSXN3/TR`++## CAD (KiCad official)++- Symbol: `SGM803-SXN3L`+- 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:** [SGMICRO datasheet](docs/sgm803-sxn3l-datasheet.pdf) (13 pp, sha256 `5e64accde249a9f4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
