NCP1117STAT3G

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

NCP1117STAT3G from onsemi, in a SOT-223. 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.

Same part, different packaging or reel option.

  • NCP1117STAT3G
  • NCP1117STAT3GDT

CAD (KiCad official)

  • Symbol: NCP1117STAT3G
  • Footprint: Package_TO_SOT_SMD:SOT-223-3_TabPin2
  • 3D model: SOT-223 (KiCad packages3D, STEP)
  • 3D model files: ncp1117stat3g-etched.step / ncp1117stat3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ncp1117stat3g.step / ncp1117stat3g.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ncp1117stat3g.step 64 KB You want the bare part, or you mark your own boards.
ncp1117stat3g-etched.step 1.9 MB You want the part with NCP1117STAT3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 488 faces against 75 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
