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 | VSS | power_in | Ground reference (0 V). Common return for supply and output. |+| 2 | VOUT | output | Voltage detection output pin, CMOS push-pull, active-low. Asserts low when VDD falls below -VDET (2.63 V); returns high after the internal 210 ms (typ) release delay once VDD recovers above -VDET+VHYS. |+| 3 | VDD | power_in | Positive supply and monitored input. Operating range 0.95 V to 7.0 V; absolute max VSS-0.3 V to VSS+8 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | SOT-23-3L |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `CJ809C263MM`+- `CJ809C263MN`+- `CJ809C263MP`++## CAD (KiCad official)++- Symbol: `CJ809C263M`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Changjing datasheet](docs/cj809c263m-datasheet.pdf) (7 pp, sha256 `4ee2baf6f08f1bd1`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
