Reset
The Reset pin informs e.g. the microcontroller in case the output voltage has fallen below
the lower threshold VRT of typ. 4.65 V. The hysteresis is typically 100mV. Connecting the
regulator to a battery voltage at first the reset signal remains LOW. When the output
voltage has reached the reset threshold VRT the reset output RO remains still LOW for
the reset delay time trd adjustable in 2 steps via the DT Pin. Afterwards the reset output
turns HIGH.
