TL431LIAEDBZRQ1

Texas Instruments · Voltage Reference · SOT-23-3

TL431LIAEDBZRQ1 from Texas Instruments, in a SOT-23-3. 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 cathode output voltage (2.495V to 36V) with shunt current sink (0.6mA minimum, 15mA maximum).
2 REF input Reference input threshold relative to anode; requires minimum 0.4µA input current for proper biasing of the internal reference amplifier.
3 ANODE power_in Ground/common anode reference pin; all circuit potentials referenced relative to this pin.
