Input capacitor

A minimum 1

µF ceramic capacitor is recommended for

designing with the MIC2288. Increasing input capacitance

will improve performance and greater noise immunity on the

source. The input capacitor should be as close as possible to

the inductor and the MIC2288, with short traces for good

noise performance.

Feedback Resistors

The MIC2288 utilizes a feedback pin to compare the output

to an internal reference. The output voltage is adjusted by

selecting the appropriate feedback resistor values. The de-

sired output voltage can be calculated as follows:
