NCV1117DTARKG

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

NCV1117DTARKG from onsemi, in a DPAK. 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 ADJ/GND input Adjust pin (adjustable version) or Ground (fixed-voltage versions). On adjustable devices, this pin sinks ~52 uA (120 uA max) and sets Vout via an external resistor divider referenced to the 1.25 V Vref. On fixed devices, this pin is the device ground return.
2 VOUT power_out Regulated positive output. Delivers up to 1.0 A continuous with typical current limit of 1.5 A (2.2 A max). Requires a 10 uF output capacitor for stability. The DPAK heatsink tab is internally connected to this pin.
3 VIN power_in Unregulated positive input supply, maximum 20 V. Requires a 10 uF input capacitor. Dropout voltage is typically 1.07 V at 800 mA and 1.2 V max over temperature.

CAD (KiCad official)

  • Symbol: NCV1117DTARKG
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: DPAK (KiCad packages3D, STEP)
  • 3D model files: ncv1117dtarkg-etched.step / ncv1117dtarkg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ncv1117dtarkg.step / ncv1117dtarkg.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ncv1117dtarkg.step 119 KB You want the bare part, or you mark your own boards.
ncv1117dtarkg-etched.step 1.6 MB You want the part with NCV1117DTARKG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 450 faces against 83 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:

  • Datasheet: onsemi datasheet (19 pp, sha256 97464a6bb19c8d03, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
