TL432ASF

HTC Korea TAEJIN Tech · Voltage Reference · SOT-23

TL432ASF from HTC Korea TAEJIN Tech, 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. The internal error amplifier compares this pin against the 1.24V internal bandgap; when driven above 1.24V the cathode sinks current to regulate. Typical reference input current 0.25uA.
2 A power_in Anode. Ground return for the shunt regulator; cathode current flows out of this pin to the negative supply.
3 K power_in Cathode. Input supply / regulated node; sinks 0.1mA to 100mA to hold VKA = VREF (or a programmed multiple set by an external divider). Max VKA = 20V (absolute), 18V recommended.

CAD (KiCad official)

  • Symbol: TL432ASF
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tl432asf-etched.step / tl432asf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tl432asf.step / tl432asf.glb are the bare package body.

Provenance

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