LD39300 does not shutdown properly (output floats)

Question asked by abufadel.amer on Jul 16, 2013
Hello all,
  I have an issue with one of the linear regulators, LD39300 (PPAK), that I am using to provide 3.7V. When the INH pin is set low (with a jumper wire to ground), the output floats at about 1V.  On a previous version of the same PCB design, the output goes all the way down to 0V when INH is low.
  Has anyone come across an issue like this that may be to shed some light on a solution?

Thank you for your time and help.
