Note 8.

All the input and output capacitors are the suggested values, referring to the effective capacitances, subject to any de-

rating effect, like a DC bias.

Note 9.

The decoupling capacitor C1 is Remote COUT capacitor. C1 is optional. The device is designed to operate with a DC

supply voltage in the range 2.2V to 5.5V. If the input supply is more than a few centimeters from the device, we recommend

you add some bulk capacitance to the ceramic bypass capacitors. A 47

F electrolytic capacitor is a typical selection for

the bulk capacitance.

Note 10.

The decoupling capacitor C3 is recommended to reduce any high frequency component on VIN bus. C3 is optional

and used to filter any high frequency component on VIN bus.
