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.
