Capacitor Selection
A 10µF capacitor is recommend for C
mended. X5R and X7R ceramic capacitors are recommend as they retain capacitance over wide ranges of voltages
and temperatures.
Output Capacitor Selection
Low ESR capacitors should be used to minimize V
they have extremely low ESR and are available in small footprints. A 4.7 to 10µF output capacitor is sufficient for most
applications. Larger values up to 22µF may be used to obtain extremely low output voltage ripple and improve tran-
sient response. The rated voltage of the capacitor should not be lower than the output voltage.
Table 5. Recommended Output Capacitors
Input Capacitor Selection
Low ESR input capacitors reduce input switching noise and reduce the peak current drawn from the battery. Ceramic
capacitors are recommended for input decoupling and should be located as close to the device as is practical. A 10µF
input capacitor is sufficient for most applications. Larger values may be used for a better stabilization of the supply volt-
age.
