Absolute Maximum Ratings
Note:
Absolute maximum ratings are DC values beyond which the device may be damaged or have its useful life impaired. The datasheet
specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and
output/input loading variables. Pericom does not recommend operation outside datasheet specifications.
1. The input negative voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.

PD
is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption
(I
CCD
) at no output loading and operating at 50% duty cycle (see Figure 2). C
PD
is related to I

dynamic operating current by
the expression: I
