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 12 V output (up to 300 mA). Requires an output capacitor between OUT and GND placed close to the pin for stability and best transient response. |+| 2 | IN | power_in | Unregulated input supply, 2.5 V to 36 V (absolute max 40 V). Bypass with the recommended input capacitor placed as close as possible to the IN and GND pins to minimize input impedance. |+| 3 | GND | power_in | Regulator ground / return reference for both input and output capacitors. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | SOT-89-3L |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `CJ75LC0S`++## CAD (KiCad official)++- Symbol: `CJ75LC0S`+- 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/cj75lc0s-datasheet.pdf) (36 pp, sha256 `c4e87b13b4aa0863`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
