Output Voltage
The output voltage on the MIC26903 evaluat
adjustable. It is set by adjusting the
(R4 and one of R5, R6, R7, R8, R9, R10, R11, o
and can be calculated as follows as an example:
where V
The output voltage above is set at the fa
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

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 MIC26903
