need help on regulator

[extraord]

I only have a 5v supply , and I need generate the 3.3v supply to drive the
the digital cicuit working at the frequency 100k, the max current is 5mA
for all the Precess , temp(-40~125), volatage(4.5~5.5). I need the 3.3v output
varies within 10%.

the question is: I have to use a 130nm TSMC process ,all the VGS or VGD of the transistor need less than 3.6v. how can I do that?

Does anyone have some comments ,thank you.

srry, i no quite clear about the TSMC process, but u can use the IC LM1117 - 3.3 to generate 3.3v from 5 v source.

Perhaps, you posted to the wrong message board? If I am understanding your question right, you want to fabricate this regulator in inside another piece of silicon? If so, then probably Hobby Circuits is not the right place.
