LP5912: Behavior of EN pin

Part Number: LP5912

Hi Team,

If the voltage of the EN pin is more than OFF Threshold and less than ON Threshold(0.3 V < VEN < 1.3 V)

What voltage will VOUT output?

Best Regards,
Tom

    Hi Tom,  

    What is the Voltage for EN that is between (0.3 V < VEN < 1.3 V)? 

    To ensure proper operation the device has to meet these requirements, otherwise the Vout state is unknown. We have seen similar questions in the past in which some LDOs "turn on" in a voltage between the given range, however, it could be that some parts of the internal circuitry are not completely ON, leading to improper operation. 

    Therefore, to ensure that all the internal circuitry is ON and the device to behave as intended then VEN > 1.3V, and to properly turn off the device VEN<0.3.

    Best,
