ME2803A28M3G

MICRONE · Supervisor and Reset ICs · SOT-23

ME2803A28M3G from MICRONE, in a SOT-23. 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 VOUT output CMOS output voltage. Follows VIN when VIN is above the detect release voltage (+VDET); pulled to GND when VIN falls below the detect voltage (-VDET). Maximum output current 50mA (absolute max); typical Iout N-ch 0.14mA and P-ch 3.4mA at VDS=0.5V.
2 GND power_in Ground reference (0V). All internal reference and output stages are referenced to this pin.
3 VIN power_in Input supply and monitored voltage. Operating range 0.7V-7V (absolute max 8V). The internal comparator monitors this pin against the trimmed -VDET reference (2.8V for this variant).

CAD (KiCad official)

  • Symbol: ME2803A28M3G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: me2803a28m3g-etched.step / me2803a28m3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me2803a28m3g.step / me2803a28m3g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
me2803a28m3g.step 59 KB You want the bare part, or you mark your own boards.
me2803a28m3g-etched.step 2.6 MB You want the part with ME2803A28M3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 606 faces against 69 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 (12 pp, sha256 aaae3b5e8fdc0db2, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
