The circuit attached is a charger for lithium cells, I understand how the circuit generally works sort of....
but what was the need for the capacitors if I may ask? what is their role in the circuit?

Thank you

hi ah,
It is not primarily intended as noise prevention, but it will give some noise reduction at the higher frequencies.
Most regulators must be fitted with decoupling capacitors as close as possible to the regulator in order prevent oscillations/instability problems within the regulator.
It is good practice to fit these capacitors.
