ME2801A33M3G

MICRONE · Supervisor and Reset ICs · SOT-23-3

ME2801A33M3G from MICRONE, in a SOT-23-3. 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 (reset/detect output). Follows VIN when VIN > VDF (~3.3V); pulled to VSS (GND) when VIN falls below VDF. Absolute-max output range Vss-0.3V to Vin+0.3V for CMOS configuration. Output sink current (N-ch, VDS=0.5V) typ 7.7 mA at VIN=2.0V; source current (P-ch, VDS=2.1V) typ -10 mA at VIN=8.0V. Max continuous IOUT rating 50 mA.
2 GND power_in Ground / VSS reference for the detector. Common return for both the VIN supply and the VOUT output driver.
3 VIN power_in Input supply and monitored voltage. Operating voltage range 0.7V to 7V (absolute max 8V). Also the sensed node compared against the internal 3.3V detect threshold. Supply current (Iss) typ 0.9 uA at Vin=3.0V, 1.0 uA at Vin=4.0V.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
me2801a33m3g.step 59 KB You want the bare part, or you mark your own boards.
me2801a33m3g-etched.step 2.4 MB You want the part with ME2801A33M3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 578 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 (9 pp, sha256 9318f4641aa05d0f, 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).
