8.2.8 5-V Regulator With Error Flags for Low Battery and Out of Regulation With Snap-ON or Snap-OFF

Output

Figure 43 is the circuit as 5-V regulator with error flags for low battery and out of regulation with Snap-ON/Snap-

OFF output. It has the following features:

•

Connect to logic or microprocessor control inputs.

•

LOW BATT flag warns the user that the battery has discharged down to about 5.8 V, giving the user time to

recharge the battery or shutdown 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 4.7 V, which could occur from a load

fault.

•

OUTPUT has Snap-ON or Snap-OFF feature. Regulator snaps ON at about 5.7-V input, and OFF at about

5.6 V.
