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 shut down hardware with high power requirements. The output is still in regulation at this time.
OUT OF REGULATION flag goes low if the output goes below about 4.7V, which could occur from a load fault.
OUTPUT has SNAP-ON/SNAP-OFF feature. Regulator snaps ON at about 5.7V input, and OFF at about 5.6V.
