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 / common return. On the fixed-output SK1117-3.3 version this pin is the device ground reference (labeled VSS/ADJ in the pinout table; on the ADJ part it is the feedback ADJ pin, on fixed parts it is GND). Tie to the single-point ground of the application. |+| 2 | VOUT | power_out | Regulated 3.3V output (3.234V min / 3.3V typ / 3.366V max at 0<=Iout<=1A, Vin=4.6V). Requires a 10uF tantalum bypass capacitor to ground for stability. |+| 3 | VIN | power_in | Unregulated input supply. Typical 15V, absolute max 18V; must be at least Vout + Vdrop (Vdrop ~1.1V at 1A). Recommend a 10uF tantalum bypass capacitor to ground. |+| 4 | VOUT | power_out | Regulated 3.3V output tab (large SOT-223 heat-slug pad, internally connected to pin 2). Also serves as the primary thermal dissipation path; solder to a copper pour to lower thermal resistance (SOT-223 theta_JC ~20 C/W). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shikues |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `SK1117-3.3`++## CAD (KiCad official)++- Symbol: `SK1117-3.3`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Shikues datasheet](docs/sk1117-3-3-datasheet.pdf) (10 pp, sha256 `e3e5f9a414ebb08b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
