Sink Current Capability, 1mA to 100mA  
Low Reference Pin Current  
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  
dividerresistorsallowtheLT1431tobeconfiguredasa5V  
shunt regulator, with 1% initial voltage tolerance and  
requiring no additional external components. By adding  
twoexternalresistors,theoutputvoltagemaybesettoany  
value between 2.5V and 36V. The nominal internal current  
limit of 100mA may be decreased by including one exter-  
nal resistor.
