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 | OUT | power_out | Regulated 3.3V output, up to 300 mA. Requires an output capacitor between OUT and GND, placed as close to the pin as possible for best transient response. |+| 2 | GND | power_in | Regulator ground reference. On SOT-89 this pin is fused to the die-pad tab and should be tied to a large ground copper for thermal dissipation. |+| 3 | IN | power_in | Unregulated input supply, 2.5V to 36V. Place a 1µF (or larger) input capacitor as close as possible to IN and GND to minimize input impedance and improve transient response. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | SOT-89-3L |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `CJ75L033S`+- `CJ75L05S`+- `CJ75LC0S`++## CAD (KiCad official)++- Symbol: `CJ75L033S`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-3L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Changjing datasheet](docs/cj75l033s-datasheet.pdf) (36 pp, sha256 `c4e87b13b4aa0863`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
