Output Voltage
The output voltage on the MIC26901 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 limitation
on line regulation. Please refer to the “Setting Output
Voltage” section of the MIC26901 datasheet for more
