immunity on the source. The input capacitor should be
as close as possible to the inductor and the MIC2601,
with short traces for good noise performance.
Feedback Resistors
The MIC2601/2 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
MIC2601/2
or equal to 1kΩ (R2 ≤ 1kΩ). The desired output voltage
can be calculated as follows:
V_OUT
= V_REF
⋅ ⎜⎛ ^R1 + 1⎟⎞
⎝ ^R2 ⎠
where V_REF is equal to 1.25V.
