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, 7 V to 25 V typical (35 V absolute max). Bypass with a 0.33 μF ceramic capacitor to GND placed close to the pin for stability. |+| 2 | GND | power_in | Common ground reference for input and output. On TO-252-2L this pin is also the tab (die attach paddle), providing the primary thermal path to the PCB copper. |+| 3 | OUT | power_out | Regulated +5 V output (4.75-5.25 V over temperature) with up to 1.5 A peak current. Bypass with a 0.1 μF ceramic capacitor to GND close to the pin to improve transient response. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu |+| Package | TO-252-2(DPAK) |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `CJ7805 3%`+- 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:** [Jiangsu datasheet](docs/cj7805-3-datasheet.pdf) (4 pp, sha256 `5e06db23b2ae354d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
