MMTL432

CBI · Voltage Reference · SOT-23-3L

MMTL432 from CBI, in a SOT-23-3L. 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. Connected to the internal comparator input; the device regulates the cathode voltage such that Vref (typ. 1.2400 V, guaranteed 1.2214-1.2586 V) appears between REF and ANODE. Reference input current is ~0.6 µA (max drift over temperature) with 6 µA absolute max.
2 CATHODE power_in Cathode (K) terminal of the shunt regulator. Sinks current from the load; operating cathode voltage range up to VKA = 18 V max, continuous cathode current up to 100 mA, minimum cathode current for regulation 0.1 mA. Dynamic impedance ~0.5 Ω at f ≤ 1 kHz.
3 ANODE power_in Anode (A) terminal, typically connected to circuit ground/common. Serves as the return path for cathode sink current and the reference voltage return.

Ordering variants

Same part, different packaging or reel option.

  • MMTL432

CAD (KiCad official)

  • Symbol: MMTL432
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: mmtl432-etched.step / mmtl432-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmtl432.step / mmtl432.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mmtl432.step 59 KB You want the bare part, or you mark your own boards.
mmtl432-etched.step 1.1 MB You want the part with MMTL432 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 285 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: CBI datasheet (5 pp, sha256 cb6dcff353cf17ee, 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).
