Are you saying it opens too far? If so there are several door stops ranging from rubber cups that stick on the wall to prevent the door from banging holes in the wall to the spring stop used on many screen doors. this is a chain and spring affair when the door reaches the limt the chain is pulled tight and the spring is compressed stopping any additional swing.
Where to get 'em. Any hardware store
Do I recommend them.. Likely no.. Depending on the install they may put a lot of "Torque" on the door when it hits the stop. this could, long term, be a serious problem.
Home is where I park it!
