SK1117-5.0

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

SK1117-5.0 from Shikues, 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 return for the regulator. On the fixed-output SK1117-5.0 variant this pin is the device ground (labeled VSS/ADJ in the pin table; the ADJ function only applies to the SK1117-ADJ variant).
2 VOUT power_out Regulated 5.0V output. Typical output is 5.0V (min 4.9V, max 5.1V) at 0 to 1A load with Vin=6.3V. Requires a ~10uF tantalum output capacitor for stability.
3 VIN power_in Unregulated input supply. Recommended operating input voltage is up to 15V (absolute max 18V). Recommend a 10uF tantalum bypass capacitor from VIN to GND.
4 VOUT power_out Regulated 5.0V output (SOT-223 tab). Electrically connected to pin 2; the large tab also serves as the primary thermal path (theta_JC = 20 C/W).

Two STEP files. Same geometry, different body top:

File Size Use it when
sk1117-5-0.step 64 KB You want the bare part, or you mark your own boards.
sk1117-5-0-etched.step 1.4 MB You want the part with SK1117-5.0 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 369 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:

  • Datasheet: Shikues datasheet (10 pp, sha256 e3e5f9a414ebb08b, retrieved 2026-08-17, tier: lcsc)
  • 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).
