TL431CLP

Texas Instruments · Voltage Reference · TO-92-3

TL431CLP 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 parallel-shunt output node programmable from Vref (~2.5V) to 36V with current-sinking capability of 1 mA to 100 mA.
2 ANODE power_in Common anode/ground reference terminal serving as the return path for cathode current sink.
3 REF input Feedback input pin for output voltage programming that is forced to internal reference voltage (~2.5V) in regulation mode and requires minimum 4 µA input current.
