NMOS LDO stability question

[Lt_Garillios]

Hi,

I picked up that a LDO with an NMOS pass transistor is inherently stable at hight loads, but not at small loads, could somebody explain this in comparision to a PMOS pass transistor?

Cheers,

Dear Lt_garillios

You read this thesis to understand your problem. I think this one is good design LDO with an NMOS
