Bypass Capacitor Notes:
1. Input capacitor C_IN is typically chosen based on the ripple current requirements. C_OUT is typically selected based on both
current ripple rating and ESR requirement. See AN-6006 for these calculations.
2. C7, C12, and C15 selection is largely determined by ESR and load transient response requirements. In each case, the
number of capacitors required depends on the capacitor technology chosen. Oscons can meet the requirements with less
space, but higher cost, than using low-ESR electrolytics.
