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 +8 V output (Vo = 7.6-8.4 V). Rated for continuous output current up to 100 mA. Requires a bypass capacitor (typ. 0.1 µF) to ground placed close to the pin for stability and transient response. |+| 2 | GND | power_in | Common ground reference for input and output. Also serves as the thermal tab connection on the SOT-89-3L package (die-attach flag). |+| 3 | IN | power_in | Unregulated input supply, Vi up to 30 V absolute max (recommended operating range ≥ ~10.5 V for full regulation to 8 V). Requires an input bypass capacitor (typ. 0.33 µF) close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `CJ78L08`+- 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/cj78l08-datasheet.pdf) (1 pp, sha256 `cd5764838a01b2a4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
