Aircraft X was on a high 2 mile to a mile and a half final. Aircraft X broke out of the clouds at 1700 ft. At that point I realized that Aircraft X was not going to make the descent and sent Aircraft X around; and I issued Aircraft X a 275 heading and to climb to 2500 feet. Prior to me issuing the go around; Aircraft Y was on departure roll and on a diverging course (PADRZ departure). In my opinion the distance between Aircraft X and Aircraft Y was no factor for each other. As Aircraft X started their climb; Aircraft Y increased their speed and they over took Aircraft X. When I noticed the overtake; I had Aircraft Y stop their climb at 1500 feet to provided positive separation until Aircraft Y was established on their SID and diverging. Once divergence was established; I instructed Aircraft Y to continue their climb to 15000 and switched both aircraft to departure control. By me stopping the climb of Aircraft Y at 1500 feet; Aircraft Y was below the MVA for the area he was in which is 1900ft. When I first noticed Aircraft X was not going to make the approach; I should of turned Aircraft X to a 250 heading coordinated with the adjacent airport (NZY) and established diverging course further out and much sooner.
SAN Tower Controller reported sending an aircraft around; which then caused the controller to stop a departure below the Minimum Vectoring Altitude to maintain separation between the two aircraft.
