TL1431CLPR

Texas Instruments · Voltage Reference · TO-92-3

TL1431CLPR from Texas Instruments, in a TO-92-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CATHODE output Regulated output terminal with voltage adjustable from 2.5V to 36V relative to anode and cathode current sourcing capacity of 1mA to 100mA.
2 ANODE power_in Ground reference terminal serving as the common return path for cathode current.
3 REF input Reference voltage input terminal with internal threshold of approximately 2.5V relative to anode ground.

CAD (KiCad official)

  • Symbol: TL1431CLPR
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92-3 (KiCad packages3D, STEP)
  • 3D model files: tl1431clpr-etched.step / tl1431clpr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tl1431clpr.step / tl1431clpr.glb are the bare package body.
