8.2.15.9 Circuit Using Ceramic Output Filter Capacitors

Figure 8-5 shows an application circuit using all ceramic capacitors for the input and output filters which generates a 3.3-V output from a 10-V to 24-V input. The design procedure is similar to those given for the design example, except for the selection of the output filter capacitor values and the design of the additional compensation components required to stabilize the circuit.
