I have a project in which I need both 5V and 3V3 rails for different chips. For the 5V supply I have before the 5V regulator a 47uF capacitor, then after the 5V regulator another 47uF capacitor as well as a 0.1uF capacitor. The 5V supply described above feeds the 3V3 power supply, which has before…

5V to 3V3 capacitor question

I always followed Bob Pease's stuff in the old NatSemi days and still have a very well thumbed old copy of the linear databook...

ah well

Allan.
