The TLV431Q is a three-terminal adjustable shunt regulator offering excellent temperature stability and output current handling capability up to 20mA. The output voltage may be set to any chosen voltage between 1.24 and 18 volts by selection of two external divider resistors.
The TLV431Q can be used as a replacement for Zener diodes in many applications requiring an improvement in Zener performance.
The TLV431Q is available in 3 tolerance bands with initial tolerances of 1%, 0.5%, and 0.2% for the A, B and T bands respectively.
The TLV431Q is qualified to AEC-Q100 Grade 1 and is automotive-compliant supporting PPAP documentation.
