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 | INPUT | power_in | Unregulated positive input supply. For the 5V variant (KIA7805) VIN max is 35V; recommended operating VIN 7.0V to 25V. Dropout voltage ~2.0V at IOUT=1A. |+| 2 | GND | power_in | Common ground reference for input and output. Also the thermal path - tab is electrically isolated on TO-220IS (fully-molded / isolated variant). |+| 3 | OUTPUT | power_out | Regulated +5V output (typ 5.0V, 4.8V-5.2V at IOUT=100mA, Tj=25°C). Short-circuit current limit ~1.6A. Compatible with MLCC, tantalum, and low-ESR electrolytic output capacitors. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | KEC Semicon |+| Package | TO-220F-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `KIA7805API-UAPI`+- `KIA7805API-UAF`++## CAD (KiCad official)++- Symbol: `KIA7805API-U`+- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`+- 3D model: TO-220F-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [KEC Semicon datasheet](docs/kia7805api-u-datasheet.pdf) (20 pp, sha256 `edd644632a33a22d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
