Note 3: CPD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption (ICCD) at no output
loading and operating at 50% duty cycle. (See Figure 12) CPD is related to ICCD dynamic operatic current by the expression:
ICCD (CPD)(VCC)(fin) (ICCstatic).
