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 terminal. All voltages in the datasheet are referenced to this pin. Connect directly to system ground and to the negative terminals of CIN and COUT. |+| 2 | IN | power_in | Unregulated input supply pin (VIN). Operating range 2.5V to 60V (absolute max -0.3 to 65V). Decouple with a 1.0μF or larger low-ESR capacitor placed as close as possible to the pin. |+| 3 | OUT | power_out | Regulated 12V output (VOUT) capable of sourcing up to 150mA (400mA absolute max). Dropout is 500mV at 50mA (for the 3.3V option). Requires a 1.0μF or larger output capacitor (10μF recommended) with good frequency characteristics for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | SOT-89-3L |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `CJ88120`+- 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/cj88120-datasheet.pdf) (8 pp, sha256 `c2050774e448f2b1`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
