5V Regulator with Error Flags for

LOW BATTERY and OUT OF REGULATION

with SNAP-ON/SNAP-OFF Output

01112723

* 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.
