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 return for the regulator. On the fixed-output SSP1117-3.3V this pin is the device ground reference; on the ADJ variant the same pin becomes the ADJ feedback node. |+| 2 | VOUT | power_out | Regulated 3.3V output. Sources up to 1A load current. Requires a 10uF tantalum output capacitor for stability. |+| 3 | VIN | power_in | Unregulated input supply. Recommended maximum 20V, absolute max 30V. For the 3.3V output, minimum operating Vin is 4.8V with a 10uF tantalum bypass capacitor recommended. |+| 4 | TAB | power_out | SOT-223 heat-slug tab, internally connected to VOUT. Solder to a copper pour to reduce thermal resistance (package thermal resistance is 20 °C/W). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shanghai |+| Package | SOT-223-3 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `SSP1117-3.3VL`+- `SSP1117-3.3VO`++## CAD (KiCad official)++- Symbol: `SSP1117-3.3V`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Shanghai datasheet](docs/ssp1117-3-3v-datasheet.pdf) (9 pp, sha256 `4548d0eb79d83846`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
