LT3028
APPLICATIO N S I N FOR M ATIO N
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.
When the IN pin of the LT3028 is forced below either OUT
pin or either OUT pin is pulled above the IN pin, input current
for the corresponding regulator will typically drop to less
than 2 μ A. This can happen if the input of the device is
connected to a discharged (low voltage) battery and the out-
put is held up by either a backup battery or a second regu-
lator circuit. The state of the SHDN1/SHDN2 pin will have
no effect on the reverse output current when the output is
pulled above the input.
