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 variants (including the 5.0 V ST50 option), pin 1 is Ground; on the adjustable variant this pin functions as the Adjust feedback node biased at ~1.25 V. Typical quiescent current at Vin=15 V is 6.0 mA. |+| 2 | VOUT | power_out | Regulated 5.0 V output pin. Provides up to 1.0 A continuous output current with typical current limit ~1500 mA. Requires a 10 uF output capacitor for stability. The SOT-223 heatsink tab is internally connected to this pin. |+| 3 | VIN | power_in | Unregulated input supply pin. Operating range for the 5.0 V option is 6.5 V to 15 V; absolute maximum input voltage is 20 V. A 10 uF input capacitor is recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `NCV1117ST50T3GST50T3G`+- `NCV1117ST50T3GDT50`++## CAD (KiCad official)++- Symbol: `NCV1117ST50T3G`+- 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:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/ncv1117st50t3-d.pdf) (20 pp, sha256 `c962358436ca7db6`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
