tl432aidbzr.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 3 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

TL432AIDBZR

Texas Instruments · Voltage Reference · SOT-23-3

TL432AIDBZR 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/threshold input. Internal error amplifier compares this pin's voltage to the internal 2.495 V bandgap reference. Typical Iref = 2 µA, max 4 µA (10 µA absolute max). Setting REF equal to Vref (2.495 V) with an external resistor divider between CATHODE and ANODE programs the regulated cathode voltage VKA = Vref × (1 + R1/R2).
2 CATHODE passive Shunt current/voltage input (K). Sinks 1 mA to 100 mA (150 mA absolute max) when the device is in regulation. VKA operates from Vref up to 36 V (37 V abs max). Off-state leakage typ 0.1 µA at VKA = 36 V, Vref = 0. Dynamic impedance
3 ANODE passive Common pin (A), normally connected to circuit ground / low side of the divider. All device voltages are referenced to ANODE unless otherwise stated.

CAD (KiCad official)

  • Symbol: TL432AIDBZR
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: tl432aidbzr-etched.step / tl432aidbzr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tl432aidbzr.step / tl432aidbzr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tl432aidbzr.step 59 KB You want the bare part, or you mark your own boards.
tl432aidbzr-etched.step 1.7 MB You want the part with TL432AIDBZR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 428 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.
