Reset
The power on reset feature is necessary for a defined start of the microprocessor when
switching on the application. For the reset delay time after the output voltage of the
regulator is above the reset threshold, the reset signal is set High again. The reset delay
time is defined by the reset delay capacitor
The under-voltage reset circuitry supervises the output voltage. In case
below the reset threshold the reset output is set LOW after the reset reaction time. The
reset LOW signal is generated down to an output voltage
reaction time and the reset delay time is defined by the capacitor value.
The power on reset delay time is defined by the charging time of an external delay
capacitor
