5.5
The Reset function informs e.g. the microcontroller in case the output voltage has fallen below the lower threshold
VRT
Connecting the regulator to a battery voltage at first the reset signal remains LOW. When the output voltage has
reached the reset threshold
Afterwards the reset output turns HIGH.
