MEL7135PG

MICRONE · LED Drivers · SOT-89

MEL7135PG from MICRONE, in a SOT-89. 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 VDD power_in Supply voltage input, 2.7 V to 6.0 V (absolute max -0.3 V to 7 V). Typical quiescent current ~90 μA.
2 GND power_in Ground / VSS reference for the device. Also serves as the thermal tab on SOT-89-3 (large center pad).
3 OUT output Constant-current sink output. Connect to LED cathode (LED anode to supply). Sinks a regulated ~350 mA (MEL7135) with typical dropout of 130 mV at Vout = 0.2 V. Absolute max -0.3 V to 7 V.

CAD (KiCad official)

  • Symbol: MEL7135PG
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89 (KiCad packages3D, STEP)
  • 3D model files: mel7135pg-etched.step / mel7135pg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mel7135pg.step / mel7135pg.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
mel7135pg.step 57 KB You want the bare part, or you mark your own boards.
mel7135pg-etched.step 1.1 MB You want the part with MEL7135PG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 310 faces against 42 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 (5 pp, sha256 d94695295257fc74, 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).
