8.4 Device Functional Modes

8.4.1 Enable Operation

The LP3995 may be switched ON or OFF by a logic input at the EN pin, VEN. A high voltage at this pin turns the

device on. When the EN pin is low, the regulator output is off and the device typically consumes 3 nA. If the

application does not require the shutdown feature, the EN pin should be tied to VIN to keep the regulator output

permanently on. To ensure proper operation, the signal source used to drive the EN input must be able to swing

above and below the specified turn-on/off voltage thresholds listed in Electrical Characteristics under VIL and VIH.
