TLE7276-2 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.
