TL432AQDBZR

Texas Instruments · Voltage Reference · SOT-23-3

TL432AQDBZR from Texas Instruments, 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 REF input Reference (feedback) input. High-impedance threshold input compared internally to the 2.5 V bandgap; drives the shunt on when V(REF) exceeds Vref relative to ANODE. Reference input current I(ref) is in the µA range; input range -0.05 to 10 mA absolute max.
2 CATHODE passive Shunt current/voltage input (K). Sinks the regulated current from the load; V(KA) operating range Vref to 36 V, continuous cathode current -100 to 150 mA absolute max, 1-100 mA recommended.
3 ANODE passive Common pin, normally connected to circuit ground. All device voltages are referenced to ANODE unless otherwise noted.

CAD (KiCad official)

  • Symbol: TL432AQDBZR
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: tl432aqdbzr-etched.step / tl432aqdbzr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tl432aqdbzr.step / tl432aqdbzr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (83 pp, sha256 1604fb205e06d1fe, 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).
