* Connect to Logic or µP control inputs.
OUTPUT has SNAP-ON/SNAP-OFF feature.
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.
Td = (0.28) RC = 28 ms for components shown.
