Capacitors in parallel with voltage sources
In DC power sources, you will see large capacitors in parallel with the output used to filter the DC voltage output. In an "ideal" DC voltage source (like a fully charged car battery), putting capacitors in parallel with the battery terminals will initially change the total circuit current until the capacitor is fully charged wherein the current …
power supply
Here the second output capacitor is 0.1 uF and it is there to deal with high frequency noise. Note that having a large capacitor on the output can cause problems. If the input was shorted so that power was removed C4 would discharge back through the regulator. Depending on voltage and capacitor size this can cause damage.
