flag becomes active when V
of Reg. #2 becomes active and via Q1 latches the main output off. When V
exceeds 5.7V Reg. #1 is back in regulation and the early warning signal rises,
unlatching Reg. #2 via D3.
For 5V
Early warning flag on low input voltage
Main output latches off at lower input voltages
