Feedback Resistors
The MIC2605/6 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 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.
