TLV431BIPK

Texas Instruments · Voltage Reference · SOT-89-3

TLV431BIPK from Texas Instruments, in a SOT-89-3. 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 pin for setting output voltage through external resistive divider; requires minimum input current of 0.15 µA (typical).
2 ANODE power_in Common ground terminal normally connected to the negative supply rail or ground reference.
3 CATHODE bidirectional Shunt regulator output terminal with adjustable voltage from VREF (1.24 V) to 6 V and operating cathode current from 0.1 to 15 mA.
