DESCRIPTIO

The LT

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 3-pin version, the LT1431CZ/LT1431IZ, is

available for applications as an adjustable reference and is

pin compatible with the TL431.
