TL432AIM3

HGSEMI · Voltage Reference · SOT-23-3

TL432AIM3 from HGSEMI, 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 input. High-impedance sense input compared internally against the on-chip 2.495 V bandgap; when the divider voltage at REF reaches Vref the device begins conducting cathode-to-anode. Reference input current is typically 2 uA (max 4 uA).
2 ANODE power_in Common anode. Normally connected to ground (or the low side of the divider network) and forms the return path for the cathode shunt current.
3 CATHODE power_in Shunt current/voltage input. Sinks current from the supply through an external series/pull-up resistor to regulate Vka; continuous cathode current range is 1 mA to 100 mA (absolute max -100 to +150 mA), Vka up to 36 V (abs max 37 V).

  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: tl432aim3-etched.step / tl432aim3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tl432aim3.step / tl432aim3.glb are the bare package body.

Provenance

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

  • Datasheet: HGSEMI datasheet (26 pp, sha256 cc40a4a8815eed85, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
