How many capacitors are required 3.3 V rail for 500 mA?
Then at each digital chip that uses this power supply, put a small ceramic cap (100nF - 1µF) directly accross its power and ground pins as close as possible to the chip. This is called a "decoupling" capacitor, and is for a different purpose than the larger capacitance at the output of the power supply.
Can anyone tell me what is the maximum capacitance

Does every power pin of an IC need a decoupling capacitor?
Many IC datasheets recommend one decoupling capacitor for every power pin of the IC. That leads to schematics like the one attached. I am often facing the problem to place them such, that they are all near to their respective pins with vias in their proper place and so on, especially in this case, where many of the pins are side by side and the minimum pitch of the capacitors is
ELI5: Why are there so many capacitors on my PC''s motherboard?
Just add lots of "expansion tanks" to the plumbing network. The capacitors filter out the dips. To do their job correctly, they have to be spread out all through the network. Or in other words, each capacitor is like a small local power supply, when a chip draws a sudden surge, it takes it from the capacitor instead of from the entire network.
Why so many capacitors in parallel instead of just one?
of course it does and it can be proven through practice. And through math. the total mass of the many caps are approximately the same. if the chance of failing for each cap is the same in order to get 70% of the caps to fail is much smaller
Capacitors
Each capacitor should be accompanied by a name -- C1, C2, etc.. -- and a value. The value should indicate the capacitance of the capacitor; how many farads it has. Speaking of farads...
