APPLICATIONS INFORMATION
V OUT = V ADJ
CURRENT FLOWS
In circuits where a backup battery is required, several
different input/output conditions can occur. The output
voltage may be held up while the input is either pulled
to ground, pulled to some intermediate voltage or is left
open circuit. Current ?ow back into the output will follow
the curve shown in Figure 6.
When the IN pin of the LT3023 is forced below the OUT1
or OUT2 pins or the OUT1/OUT2 pins are pulled above the
IN pin, input current will typically drop to less than 2μA.
