TLE7272-2 Electrical Characteristics 5.3 Electrical Characteristics Enable Function The Enable Function allows disabling/enabling the regulator via the input pin EN. The regulator is turned on in case the pin EN is connected to a voltage higher than VEN,H. This can be e.g. the battery voltage, whereby no additional pull-up resistor is needed. The regulator can be turned off by connecting the pin EN to a voltage less than VEN,L, e.g. GND. Electrical Characteristics Enable VI =13.

TLE7272-2 Electrical Characteristics 5.5 Electrical Characteristics Reset Function The Reset function informs e.g. the microcontroller in case the output voltage has fallen below the lower threshold VRT of typ. 4.65 V. The headroom VRH between the output voltage and the reset threshold is typically 350 mV. Connecting the regulator to a battery voltage at first the reset signal remains LOW.
