LMV431BIMFX-TP

TECH PUBLIC · Voltage Reference · SOT-23

LMV431BIMFX-TP from TECH PUBLIC, 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 REF input Reference input. Compared internally against the ~1.24 V bandgap; drives the shunt element when REF exceeds Vref. Typical reference input current 0.7 µA (max 4 µA); absolute maximum reference input current ±10 mA.
2 CATHODE passive Cathode (K) of the shunt regulator. Sinks the regulated cathode current (0.1-100 mA operating, absolute max −100 to +150 mA). Absolute maximum cathode voltage Vka = 18 V.
3 ANODE passive Anode (A) of the shunt regulator, the device ground return. All voltage values are referenced to the anode.

Same part, different packaging or reel option.

  • LMV431BIMFX-TP

CAD (KiCad official)

  • Symbol: LMV431BIMFX-TP
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: lmv431bimfx-tp-etched.step / lmv431bimfx-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lmv431bimfx-tp.step / lmv431bimfx-tp.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
lmv431bimfx-tp.step 59 KB You want the bare part, or you mark your own boards.
lmv431bimfx-tp-etched.step 1.7 MB You want the part with LMV431BIMFX-TP already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 452 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: TECH PUBLIC datasheet (5 pp, sha256 387bb1c3545bdbd4, 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).
