Preliminary Technical Data

ADP2503/ADP2504

Input Capacitor Selection

The ADP2503/ADP2504 require an input capacitor to filter

noise on the VIN pin, and provide the transient currents while

maintaining constant input and output voltage. A 10 μF X5R/

X7R ceramic capacitor rated for 6.3 V is the minimum recom

mended input capacitor. Increased input capacitance reduces

the amplitude of the switching frequency ripple on the battery.

Because of the dc bias characteristics of ceramic capacitors, a

0603, 6.3 V X5R/X7R, 10 μF ceramic capacitor is preferable.
