The LT1431 is an adjustable shunt voltage regulator with
100mA sink capability, 0.4% initial reference voltage tol-
erance, and 0.3% typical temperature stability. On-chip
divider resistors allow the LT1431 to be configured as a 5V
shunt regulator, with 1% initial voltage tolerance and
requiring no additional external components. By adding
two external resistors, the output voltage may be set to any
value between 2.5V and 36V. The nominal internal current
limit of 100mA may be decreased by including one exter-
nal resistor.
A simplified three pin version, the LT1431Z/IZ, is available
for applications as an adjustable reference and is pin
compatible with the TL431.
