Input capacitor
A minimum 1μF ceramic capacitor is recommended for
designing with the MIC2290. 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 MIC2290,
with short traces for good noise performance.

Feedback Resistors
The MIC2290 utilizes a feedback pin to compare the
output to an internal reference. The output voltage is
adjusted by selecting the appropriate feedback resistor
network values. The R2 resistor value must be less than
or equal to 5k ? (R2 ≤ 5k ? ). The desired output voltage
can be calculated as follows:
V OUT = V REF × ?
+ 1 ?
? R1
? R2

?
where VREF is equal to 1.24V.
