Adrienne Maloof -- Granted Restraining Order Against Dr. Paul Nassif

Adrienne Maloof's estranged husband, Dr. Paul Nassif, has been ordered by the court to stay away from Adrienne and their three children ... TMZ has learned.

TMZ obtained a copy of the the temporary restraining order -- granted yesterday -- which requires Nassif to stay at least 100 yards away from Adrienne and their boys.

The order also states Nassif must stay away from Adrienne's home and the children's school.

Adrienne's TRO request was granted by the same judge who gave Adrienne temporary custody of their children yesterday.

As TMZ first reported ... Adrienne accused Paul of spanking and choking the children in her request for temporary custody.

A hearing is scheduled for October 9th to decide whether the TRO and custody orders will be made permanent.
