Notes:
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 2.) CPD is related to ICCD dynamic operating current by
the expression:
ICCD = (CPD)(VCC)(fIN) + (ICCstatic).
