NCV1117ST50T3G

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

NCV1117ST50T3G 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 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.

CAD (KiCad official)

  • Symbol: NCV1117ST50T3G
  • Footprint: Package_TO_SOT_SMD:SOT-223-3_TabPin2
  • 3D model: SOT-223 (KiCad packages3D, STEP)
  • 3D model files: ncv1117st50t3g-etched.step / ncv1117st50t3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ncv1117st50t3g.step / ncv1117st50t3g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ncv1117st50t3g.step 64 KB You want the bare part, or you mark your own boards.
ncv1117st50t3g-etched.step 2.2 MB You want the part with NCV1117ST50T3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 545 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:
