    Hi Beida,

    For these two specs, the mean value +/- 6*sigma is still within the min and max values.

    And out of spec units will be screened out at ATE test.

    Regards

    Hi Lei,

    1. How to understand the Vhys and Vt+ function for Vout? Plss see below figure description.

    2. Customer test when Ven drop to 0.8V, the Vout drop to 4V from 5V. So is it normal?

    Hi Beida,

    VT+ max 1.2V means that when the rising EN exceeds 1.2V, it's guaranteed that EN is high.

    VT- max means that when EN is falling, if it still above 0.76V, the EN is still high.

    VT- min means that when EN is falling, if it still below 0.5V, it's guaranteed that EN is low.

    I think the Vout should still be 5V if the accurate EN voltage is 0.8V.

    Regards
