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 / negative supply reference for the regulator. |+| 2 | VOUT | power_out | Regulated output. Fixed 1.2V nominal (per '12' MPN suffix); rated 500mA min / 700mA typ output current when VOUT >= 1.8V (300mA min / 500mA typ for VOUT >= 0.8V). Requires a >=1µF ceramic output capacitor. Internally current-limited and short-circuit protected (ISHORT ~= 100mA when VOUT is shorted to VSS). |+| 3 | VIN | power_in | Unregulated power input. Operating range 1.8V to 6.0V (absolute max -0.3V to 7V). Requires a >=1µF ceramic input capacitor. Typical dropout 55mV at IOUT=100mA (VOUT=3.3V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `CJ6211A12NN`+- `CJ6211A12NM`+- `CJ6211A12NF`++## CAD (KiCad official)++- Symbol: `CJ6211A12N`+- 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:** [Changjing datasheet](docs/cj6211a12n-datasheet.pdf) (11 pp, sha256 `805289572b9842e1`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
