NCV1117DT50RKG

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2

NCV1117DT50RKG from onsemi, in a TO-252-2. 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 fixed-output regulator. On the adjustable (XTA) version this pin becomes the Adjust input tied to the feedback divider; on the fixed 5.0 V (XT50) variant it is the device ground return.
2 VOUT power_out Regulated 5.0 V output. Requires a >=10 uF output capacitor for stability. Sources up to 1.0 A (1.5 A typical current limit) with 1.2 V max dropout at 800 mA. Heatsink tab is internally connected to this pin.
3 VIN power_in Unregulated input supply, 7.0 V to 15 V typical operating range for the 5.0 V variant (20 V absolute maximum). Requires a 10 uF input capacitor for stability.
TAB TAB power_out Exposed thermal tab, electrically connected to pin 2 (VOUT). Solder to a copper pour for heatsinking; RθJC = 6.0 °C/W, RθJA = 67 °C/W on minimum pad.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ncv1117dt50rkg.step 119 KB You want the bare part, or you mark your own boards.
ncv1117dt50rkg-etched.step 2.0 MB You want the part with NCV1117DT50RKG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 526 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 9eb5729f5f840f6f, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
