In some applications it may be necessary to leave the input
to the LT1529 unconnected when the output is held high.
This can happen when the LT1529 is powered from a
rectified AC source. If the AC source is removed, then the
input of the LT1529 is effectively left floating. The reverse
output current also follows the curve in Figure 3 if the V
IN
pin is left open. The state of the SHDN pin will have no
effect on the reverse output current when the V
IN
pin is
floating.
When the input of the LT1529 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 3 . This
can happen if the input of the LT1529 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.
When the V
IN
pin is forced below the OUTPUT pin or the
OUTPUT pin is pulled above the V
IN
pin, the input current

will typically drop to less than 2
μ
A (see Figure 4). The state
of the SHDN pin will have no effect on the reverse output
current when the output is pulled above the input.
