4 / 7 page  www.fairchildsemi.com 4 AC Electrical Characteristics Note 3: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC (opr) = CPD * VCC * fN + ICC.
