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 =13.5 V; Tj = -40 °C to 150 °C; all voltages with respect to ground, positive current flowing into pin
