*Output voltage equals +V_IN minus dropout voltage, which varies with output current. Current limits at a maximum of
1000 mA (typical).
**Select R1 so that the comparator input voltage is 1.23V at the output voltage which corresponds to the desired fault
current value.

*Connect to Logic or μP control inputs.
LOW BATT flag warns the user that the battery has discharged down to about 5.8V, giving the user time to recharge
the battery or power-down some hardware with high power requirements. The output is still in regulation at this time.
OUT OF REGULATION flag indicates when the battery is almost completely discharged, and can be used to initiate a
power-down sequence.
