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 | Ground / VSS reference. Common return for input and output; tie to the system ground plane. Also serves as the exposed SOT-89 heat-sink tab for thermal dissipation. |+| 2 | IN | power_in | Unregulated input supply, VIN. Operating range 2.5 V to 36 V (absolute max 40 V). Bypass to GND with ≥1 µF ceramic or tantalum for stability and PSRR. |+| 3 | OUT | power_out | Regulated 3.3 V output, VOUT. Sources up to 300 mA (600 mA absolute max). Requires ≥1 µF ceramic or tantalum output capacitor to GND for stability and transient response. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `CJ7533SS`++## CAD (KiCad official)++- Symbol: `CJ7533S`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Changjing datasheet](docs/cj7533s-datasheet.pdf) (6 pp, sha256 `d76ea5eea44dc63d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
