Compensation network with MLCC (multiple layer ceramic
capacitor) at the output
MLCCs with values in the range of 10 µF-22 µF and rated voltages in the range of 10 V-25 V
are available today at relatively low cost from many manufacturers.
These capacitors have very low ESR values (a few mΩ) and thus are occasionally used for
the output filter in order to reduce the voltage ripple and the overall size of the application.
However, a very low ESR value affects the compensation of the loop (see
order to keep the system stable, a more complicated compensation network may be
required. The figure below shows an example of a compensation network stabilizing the
system with ceramic capacitors at the output (the optimum component value depends on
the application).
