TL431AIL3T-TP

TECH PUBLIC · Voltage Reference · SOT-23

TL431AIL3T-TP from TECH PUBLIC, in a SOT-23. 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 passive Cathode of the shunt regulator; maximum cathode voltage is 36 V and continuous cathode current range is 1.0 to 100 mA.
2 REF input Reference input that sets the output voltage via an external resistor divider, with Vref typically 2.495 V and maximum reference input current of 10 mA.
3 ANODE passive Anode of the shunt regulator, normally connected to ground; all voltage values are referenced to the anode.
