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…
