LMV331W5-7

Diodes Incorporated · Comparators · SOT-25

LMV331W5-7 from Diodes Incorporated, in a SOT-25. 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 IN+ input Non-inverting comparator input. Common-mode range: -0.1V to (VCC - 0.8V). Typical input bias current 25 nA at VCC=5V.
2 VEE power_in Chip negative supply / ground reference. Tied to 0V (GND) in single-supply operation. VCC-VEE absolute max = 5.5V.
3 IN- input Inverting comparator input. Common-mode range: -0.1V to (VCC - 0.8V). Typical input bias current 25 nA at VCC=5V.
4 OUT output Open-collector comparator output. Requires external pull-up resistor to VCC (recommended 1KΩ to 10KΩ). Sink current typ 84 mA at VO=1.5V with VCC=5V; leakage typ 3 nA.
5 VCC power_in Positive chip supply. Operating range 2.7V to 5.5V (single-supply). 0.1 µF bypass capacitor to GND recommended close to the pin.

Two STEP files. Same geometry, different body top:

File Size Use it when
lmv331w5-7.step 85 KB You want the bare part, or you mark your own boards.
lmv331w5-7-etched.step 1.6 MB You want the part with LMV331W5-7 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 401 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: Diodes Incorporated datasheet (13 pp, sha256 8153c11648b9bf3d, retrieved 2026-08-17, tier: manufacturer)
  • 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).
