Hi,
I designed a 3.3V Linear regulator using On chip's 5203A-3.
How to fix the values of i/p and o/p capacitors??
I just followed the recommendations in Data sheet and applied 22uF (High ESR-electrolytic) capacitor at the output and a 100nF ceramic capacitor at the input.
What is method used to calculate these values ??
How to arrive at the apt values of capacitors needed from the load requirements??
What is the role played by this high value o/p capacitor?? its ESR is large and they dont supress ripple or not a good vicinity source , then y use them....
please help
