MM108 input voltage

Hi,
I would like to know the supply voltage tolerance of the MM108 module.
On the documentation it is indicated 12 Vpp, until which tension can we use this converter? is an input voltage of 13.5V - 14V too high?

Best regards,
Sandrine

14V is just reaching the absolute limit of the voltage regulator.
It should work but ofcourse be aware!
