TLVH431AIDBZR-TP

TECH PUBLIC · Voltage Reference · SOT-23

TLVH431AIDBZR-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. Feedback input compared internally against the 1.24 V bandgap reference. Connect to the tap of an external R1/R2 divider between CATHODE and ANODE to program the output voltage: V_KA = V_REF*(1 + R1/R2) + I_REF*R1. Reference input current typ. 0.7 uA (max 4 uA).
2 ANODE power_in Anode. Ground/return terminal of the shunt regulator. All voltages in the datasheet are referenced to this pin.
3 CATHODE power_in Cathode. Regulated shunt terminal; sinks the programmed cathode current from the external bias resistor. V_KA up to 18 V absolute max; continuous cathode current 0.1-100 mA (abs max -100 to +150 mA). Dynamic impedance typ. 0.05 Ω.

Same part, different packaging or reel option.

  • TLVH431AIDBZR-TP

CAD (KiCad official)

  • Symbol: TLVH431AIDBZR-TP
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tlvh431aidbzr-tp-etched.step / tlvh431aidbzr-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlvh431aidbzr-tp.step / tlvh431aidbzr-tp.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tlvh431aidbzr-tp.step 59 KB You want the bare part, or you mark your own boards.
tlvh431aidbzr-tp-etched.step 1.9 MB You want the part with TLVH431AIDBZR-TP already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 515 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 7f60b32bcf014ed7, 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).
