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 fixed-voltage versions (e.g. NCP1117DT50) this pin is the ground reference; the datasheet labels it 'Adjust/Ground' because the same physical pin serves as the ADJ node on the adjustable variant. Quiescent current (typ 6.0 mA at Vin = 15 V) returns through this pin. |+| 2 | VOUT | power_out | Regulated 5.0 V output (typ 5.000 V, ±1.0 % initial accuracy, 4.900-5.100 V over 6.5 V ≤ Vin ≤ 12 V and 0-800 mA load). Capable of delivering in excess of 1.0 A with typical 1500 mA short-circuit current limit. Requires a 10 µF output capacitor for stability. The heatsink tab of the DPAK package is internally bonded to this pin. |+| 3 | VIN | power_in | Unregulated positive supply input, 7.0 V to 12 V typical for 5.0 V output (absolute maximum 20 V). Requires a 10 µF input bypass capacitor. Dropout voltage is typically 1.01 V at 500 mA and 1.07 V at 800 mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | TO-252-2(DPAK) |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `NCP1117DT50RKGDT50RKG`+- `NCP1117DT50RKGST50T3G`++## CAD (KiCad official)++- Symbol: `NCP1117DT50RKG`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252-2(DPAK) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/ncp1117dt50rk-d.pdf) (17 pp, sha256 `1852f8c8cf0eb18c`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
