TL431ACLPR

Texas Instruments · Voltage Reference · TO-92-3

TL431ACLPR 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 REF input Reference input; internal threshold voltage approximately 2.5V relative to anode, typically driven by external resistor divider from output voltage.
2 CATHODE bidirectional Shunt cathode; carries regulated cathode current from 1 mA (minimum) to 100 mA (maximum), with dynamic output impedance typical 0.2 Ω.
3 ANODE power_in Common anode pin, typically connected to ground; provides reference for cathode voltage measurement and internal circuit return.

CAD (KiCad official)

  • Symbol: TL431ACLPR
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92-3 (KiCad packages3D, STEP)
  • 3D model files: tl431aclpr-etched.step / tl431aclpr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tl431aclpr.step / tl431aclpr.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (86 pp, sha256 0eb18c491f5517a3, retrieved 2026-09-29, 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).
