Hello expert,

We would like to check if output will have 0.7V when TPS25981 EN is low. May you check for us? Thanks a lot!

Best regards,

Hi Ann,

FET leakage current will be there from IN to OUT. VOUT is leakage current multiplied by output impedance. We can lower output impedance to lower leakage VOUT.
