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 reference for the regulator. On fixed-voltage versions (including SSP1117-5.0V) pin 1 is the GND return; on the ADJ variant this same pin serves as the ADJ feedback node. |+| 2 | VOUT | power_out | Regulated 5.0V output (typ, ±2%). Delivers up to 1A load current. Requires a ~10uF tantalum output capacitor for stability. |+| 3 | VIN | power_in | Unregulated input supply. Recommended max 20V (absolute max 30V). For 5.0V output, Vin must exceed Vout by the dropout voltage (~1.3V at 1A). Recommended 10uF tantalum bypass capacitor to GND. |+| 4 | TAB | power_in | SOT-223 heat-sink tab (Fin), internally connected to VOUT (pin 2). Solder to a large copper pour to reduce thermal resistance (~20°C/W with minimal copper). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shanghai Siproin Microelectronics SSP1117 5 0V |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `SSP1117-5.0VL`+- `SSP1117-5.0V50L`+- `SSP1117-5.0V50LTR`+- `SSP1117-5.0VO`+- `SSP1117-5.0V50O`+- `SSP1117-5.0V50OTR`++## CAD (KiCad official)++- Symbol: `SSP1117-5.0V`+- 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:** [Shanghai Siproin Microelectronics SSP1117 5 0V datasheet](docs/ssp1117-5-0v-datasheet.pdf) (9 pp, sha256 `4548d0eb79d83846`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
