SCJT1117B-5.0

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

SCJT1117B-5.0 from Changjing, 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 versions (including the -5.0 variant) this pin functions as GND; on the -ADJ version the same pin becomes the ADJ feedback node.
2 OUTPUT power_out Regulated 5.0V output (4.875V-5.125V over line/load). Rated for up to 1A continuous with 1.3V typical dropout. Requires a 10µF tantalum bypass capacitor to ground for stability.
3 IN power_in Unregulated input supply. Recommended operating range 6.5V-12V for the -5.0 variant (must be at least VOUT + 1.3V dropout); absolute maximum 20V, recommended max 15V. Requires a 10µF tantalum bypass capacitor to ground.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
scjt1117b-5-0.step 64 KB You want the bare part, or you mark your own boards.
scjt1117b-5-0-etched.step 1.9 MB You want the part with SCJT1117B-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: 486 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: Changjing datasheet (9 pp, sha256 cd7c4eac87f0d7a9, 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).
