shutdown pin floating (open circuit). Figure 5 shows
output current as a function of output voltage with the
input floating and the shutdown pin pulled to ground.
When the input of the LT1129 is forced to a voltage below
its nominal output voltage and its output is held high, the
output current will follow the curve shown in Figure 6 . This

can happen if the input of the LT1129 is connected to a
discharged (low voltage) battery and the output is held up
by either a backup battery or by a second regulator circuit.
Users with applications requiring lower reverse currents
should contact the factory about the availability of a
modified version of the LT1129.
