Output Voltage
The output voltage on the MIC261203 evaluation board is
adjustable. It is set by adjusting the feedback resistors (R4
and one of R5, R6, R7, R8, R9, R10, R11, or R12) and
can be calculated as follows as an example:
where V
The output voltage above is set at the factory for a 1.2V
output, but it can easily be changed by moving the jumper
to a respective position to get an indicated voltage on the
board. If a desired voltage is not shown on the board, it is
easily modified by removing R4 and R7 and replacing

them with the values that yield the desired output voltage.
Once R4 is selected, R7 can be calculated using:
For V
The output voltage should not be set to exceed 5V due to
the 6.3V rating of the output capacitor and online
regulation limitations. Please refer to the “Setting Output
Voltage” section in the MIC261203 datasheet for more
information.
