In fact, the visitors were the only team that looked like scoring in the closing stages and Farfan and then Timmy Simons wasted half-chances in the box.
Jefferson Farfan was the next PSV player to trouble Robinson, this time with a flighted free-kick that the Spurs goalkeeper could only watch as it drifted narrowly over the bar.
In other matches, Schalke beat Mainz 3-0 with Jefferson Farfan opening the scoring from the spot and new boys Fortuna Dusseldorf continued their unbeaten start with a 2-0 win at Greuther Fuerth.
Spurs boss Ramos mixed things up with 20 minutes left, replacing King with Adel Taarabt, but the hosts were indebted to a brilliant Robinson save on the stretch from Farfan's drive to keep them at least in touching distance.
