MIC2288
Input capacitor
A minimum 1µF 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:
V_OUT

V_REF

where V_REF is equal to 1.24V.
