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 | IN | power_in | Unregulated positive input voltage. Operating range must be at least Vo + dropout (~2V at 1A) up to 35V absolute maximum. A 0.33 uF ceramic bypass capacitor to GND is recommended close to the pin for stability. |+| 2 | GND | power_in | Common ground reference for input and output. On TO-252-2L the GND lead is fused to the tab (heat slug), providing the primary thermal path (RθJA = 80 °C/W). |+| 3 | OUT | power_out | Regulated +6V output (5.75 V to 6.25 V at 25 °C). Sources up to 1.5A peak with internal current-limit around 550 mA short-circuit and 2.2A peak protection. A 0.1 uF output bypass capacitor to GND is recommended for transient response. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | TO-252-2(DPAK) |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `CJ7806`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252-2(DPAK) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Changjing datasheet](docs/cj7806-datasheet.pdf) (4 pp, sha256 `5c33f28c7964ad40`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
