3. Using Ceramic Capacitor Example
When using small RESR parts such as ceramic capacitors for the output capacitance, mount a resistor (R1)
corresponding to the RESR in series with the ceramic capacitor (CL) as shown in Figure 27.
R1 differs depending on “L” value, the capacitance, the wiring, and the application (output load).
The following example shows a circuit using R1 = 100 mΩ, output voltage = 3.3 V, output load = 500 mA and its
characteristics.
