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 | Adjust | input | Adjust pin for the adjustable output version. Tie a resistor divider between Output and Adjust to Ground to program Vout = Vref*(1+R2/R1) + Iadj*R2, where Vref ≈ 1.25 V and Iadj ≈ 52 µA typ (120 µA max). On fixed-voltage variants this pin is instead the Ground reference. |+| 2 | Output | power_out | Regulated output, up to 1.0 A continuous (typ current limit 1.5 A). No minimum load required on fixed-output devices; adjustable device requires IL(min) ≈ 0.8 mA (5.0 mA max). Recommended 10 µF output capacitor. Electrically connected to the heatsink tab. |+| 3 | Input | power_in | Unregulated input supply, absolute max 20 V. Dropout is 1.2 V max at 800 mA (0.95 V typ at 100 mA). Recommended 10 µF input capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `NCP1117STAT3GSTAT3G`+- `NCP1117STAT3GDT`++## CAD (KiCad official)++- Symbol: `NCP1117STAT3G`+- 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/ncp1117stat3-d.pdf) (16 pp, sha256 `57df0e5c8e889692`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
