Oscillation prevention capacitors.
• Insert the capacitors as close to the IC as possible to
decrease the power impedance for reliable IC operation
(use of electrolytic capacitors are desirable).
Decoupling capacitors.
Eliminate ripple components that pass into the input side from
the power line. (Used with R03 and R04 to form a ripple filter.)
