... Unless otherwise specified, all voltages are referenced to PGND. Model Temperature Range ADP3163JRU CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADP3163 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges ...

... As long as the capacitance of the output capacitor bank is above a critical value and the regulating loop is compensated with m Analog Devices’ proprietary compensation technique (ADOPT), m the actual capacitance value has no influence on the peak-to- peak deviation of the output voltage to a full step change in the m load current ...
