Detailed Description

The output voltage may be set to any chosen voltage between 2.5 and 36 volts by selection of two external divider resistors. The devices can be used as a replacement for zener diodes in many applications requiring an improvement in zener performance. Diodes' TL431 has the same electrical specifications as the industry standard '?431 and is available in 2 grades with initial tolerances of 1% and 0.5% for the A and B grades respectively.
