LT3023
3023f
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 flow 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 2
μ
A.
This can happen if the input of the device is connected to
a discharged (low voltage) battery and the output is held
up by either a backup battery or a second regulator circuit.
The state of the SHDN1/SHDN2 pins will have no effect on
the reverse output current when the output is pulled above
the input.
