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 | Device ground reference. Connect to system ground. |+| 2 | /RESET | output | Active-low, open-drain reset output. Asserted low while VCC is below the 3.08V threshold (VTH typ, min 3.04V / max 3.13V) and held low for the reset timeout period (typ 200ms, min 140ms) after VCC rises above VTH. Requires an external pull-up (typically to the monitored supply); can sink up to 20mA (abs max) with VOL ≤ 0.3V at ISINK = 1.2mA. Guaranteed valid down to VCC = 1V; becomes high-impedance below 1V. |+| 3 | VCC | power_in | Operating voltage input and the supply rail being monitored. Recommended operating range 1.1V to 5.5V (abs max -0.3V to +6.0V). This -31 variant trips at VTH = 3.08V typ (3.04V min / 3.13V max) with ~40mV hysteresis. Bypass with a 100nF capacitor to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `APX803-31SAG-7`+- `APX803-31SAG-7APX803-31SRG-7`++## CAD (KiCad official)++- Symbol: `APX803-31SAG-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/apx803-31sag-7-datasheet.pdf) (None pp, sha256 `49f1f0449cde1d5a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
