Hello ,In real life i want to use LD1084 because it helps to get good 15V source.
unfortunetly i could not find any spice model for LD1084 so i want to use LT1084.
i looked at the two datasheet ,i see they act almos the same.
Are they good equivalent?
I am power 10GHZ system with these regulator.
A thing i dont understand is why at higher currents we get less result?
Thanks.

Hello FVM, i just want to know if i can use the LT1084 instead or to see in what region its safe to assume that the functionality is equal.

What are your requirements? Load? Noise? Cost? Availability? If they’re equivalent in the parameters that are important to you, then use either.
