DESCRIPTIO

EATURE

■

Guaranteed 0.4% Initial Voltage Tolerance

0.1Ω Typical Dynamic Output Impedance

Fast Turn-On

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.
