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 for the regulator. All output/input voltages are referenced to this pin. |+| 2 | VOUT | power_out | Regulated output voltage pin. Fixed 3.3V (A33 suffix) at up to 500-700 mA. Requires a 1µF ceramic COUT for stability; a low-ESR ceramic is recommended. |+| 3 | VIN | power_in | Unregulated power input pin. Operating range 1.8V to 6.0V (absolute max 7V). Requires a 1µF ceramic CIN close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | SOT-23-3L |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `CJ6211A33MM`+- `CJ6211A33MN`+- `CJ6211A33MF`++## CAD (KiCad official)++- Symbol: `CJ6211A33M`+- 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/cj6211a33m-datasheet.pdf) (11 pp, sha256 `805289572b9842e1`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
