ME1117A50B3G

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

ME1117A50B3G from MICRONE, 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 VSS power_in Device ground return. 0 V reference for the internal bandgap and the fixed 5.0 V output; must be tied to the system ground plane close to the output capacitor.
2 VOUT power_out Regulated 5.0 V output, sourcing up to 1.0 A typical (1.3 A current limit). Requires a ≥10 µF output capacitor with ESR between 0.25 Ω and 2.2 Ω for stability. The SOT-223 thermal tab is internally connected to this pin.
3 VIN power_in Unregulated input supply, 4.8 V to 15 V operating (20 V absolute max). Requires a ≥10 µF bypass capacitor close to the pin for regulator stability.

Two STEP files. Same geometry, different body top:

File Size Use it when
me1117a50b3g.step 64 KB You want the bare part, or you mark your own boards.
me1117a50b3g-etched.step 2.0 MB You want the part with ME1117A50B3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 506 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: MICRONE datasheet (13 pp, sha256 e26fed9e4d5c980c, 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).
