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.
