Rc) is true, as a result, the output of comparator is reverse,
and output voltage becomes to GND level. The voltage level of Point A means detector threshold voltage,
or (

Step 3. When the supply voltage is less than minimum operating voltage, the operation of output transistor
becomes indefinite, and in the case that output is pulled up to V

Rb) is true, Output of the comparator is reverse, and output voltage is
equal to the supply voltage, or (V

DET
).
The difference between released voltage and detector threshold voltage is the detector threshold hysteresis.
