I have no experience with the 10m90s.
I use the 10m45s and sometimes the dn2540.
Have you replaced the 10m90s?
BTW Neither the 10m45s or the 10m90s is a MosFet.

It is depleted mode mosfet (possibly BJT-cascoded) with built-in gate protection.
I did replace the 10M90s. Somehow the input voltage is setting up the current and it wont revert back.
This is the same regulator as the 10M45s only a higher voltage rating.
It's dissipating about 6.5 watts and rated for 40
It was early....I know its not a MOSFET, I only remember reading about the diode protecting a CCS, must of been a MOSFET ckt and not the regulator.

That is all in the heat sink size. anything over a Watt bare is pushing things.
