ME6119C50M5G

MICRONE · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

ME6119C50M5G from MICRONE, in a SOT-23-5. 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 VIN power_in Power supply input. Operating range 2.5V to 18V (absolute max 18V). Bypass to VSS with a 10uF tantalum capacitor.
2 VSS power_in Ground reference for the regulator. Common return for input and output capacitors.
3 CE input Chip Enable. VCE >= 1.30V starts the regulator; VCE <= 0.8V shuts it down (shutdown current ~0V @ VCE=0V is 0 uA). Absolute max range VSS-0.3V to VIN+0.3V. Do not leave floating.
4 NC unconnected No connect. Leave floating; do not tie to any signal.
5 VOUT power_out Regulated 5.0V output (+/-2%), up to 400mA continuous. Requires a >=10uF tantalum output capacitor with ESR < 0.5 ohm for stability. Dropout ~104mV @ 100mA.

Two STEP files. Same geometry, different body top:

File Size Use it when
me6119c50m5g.step 85 KB You want the bare part, or you mark your own boards.
me6119c50m5g-etched.step 2.3 MB You want the part with ME6119C50M5G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 550 faces against 102 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 (10 pp, sha256 c7d4103d2fc6a40f, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
