When operating properly with 5V V

falls below its minimum operating voltage, approx. 1V. At this
point, the supervisor loses control, and its output may rise, only
to again follow V

When V

pulled to ground, etc. When V

If it is required that a lower value than GND + 1.0V is needed
on RESET signal during V

≤
1V, a 100K resistor may be used
on the device output to GND.
