Description

The TLV431 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 TLV431 can be used as a replacement for zener diodes in many applications requiring an improvement in zener performance. The TLV431 is available in 2 grades with initial tolerances of 1% and 0.5% for the A and B grades respectively.

Our shunt voltage regulator portfolio includes 2.5V, 1.24V, and 0.6V reference voltage devices covering consumer, computing, industrial, and automotive applications.

It includes industry standard TL431 and TL432 equivalents, as well as footprint compatible, very low minimum (knee) current for latest low standby power isolated power supplies. Additionally, it includes a well enhanced operating voltage range TLV431 (1.24V) equivalents. All of the 2.5V and 1.24V support operating temperatures up to 125°C as standard, therefore reducing the number of variants that need to be qualified and stocked.

Automotive-compliant variants are available which are qualified to AEC-Q100 Grade 1 in IATF 16949 facilities supporting PPAP documentation.
