I know this is fairly simple, and I get why these components are there. However, I do not fully understand why the certain values are picked and what the end filtering result is.
Is the inductor in series or parallel with the capacitors? It seems to be in series with them to ground, but parallel to the Vin pin (one end connected to Vcc, other to caps and Vin).
Is this a series LC filtering circuit? How would you determine which frequencies are being restricted? I know the basic equations, but not necessarily how to apply them.
I understand that the caps shunt AC to ground, and the inductors 'block' AC with high impedance. The end result is that the L and C are filtering AC noise, but why are these particular values chosen?
Why are several caps used in parallel, and why is one in front of the inductor?
On the output, why are two capacitors used, one that is 50V and one that is 25V rated?
