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 | Device ground / negative supply return. All internal references and the output feedback divider are referenced to this pin. |+| 2 | VOUT | power_out | Regulated 3.3 V output pin. Delivers up to 1.0 A (typ, 1.3 A max). Requires a ≥4.7 µF ceramic output capacitor to ground for stability. The SOT-223 tab is typically internally connected to this pin. |+| 3 | VIN | power_in | Unregulated positive supply input. Operating range 1.6 V to 6.0 V (absolute max VSS+7 V). Requires a ≥4.7 µF ceramic input capacitor to ground close to the pin. For 3.3 V output, VIN should be ≥ VOUT + dropout (≈320 mV @ 1 A). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `CJ6109A33GWGW`+- `CJ6109A33GWP`+- `CJ6109A33GWPL`+- `CJ6109A33GWM`+- `CJ6109A33GWFB`++## CAD (KiCad official)++- Symbol: `CJ6109A33GW`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Changjing datasheet](docs/cj6109a33gw-datasheet.pdf) (10 pp, sha256 `75ae8c6e825a8cea`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
