Output Voltage
The output voltage on the MIC261201 evalu
is adjustable. Set it by adjusting the
(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 th
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, modify it by removing R4 and R7

For V
The output voltage should not be set to exceed 5V due
to the 6.3V rating of the output capacitor and on-line
regulation limitation. Please refer to the “Setting Output
Voltage” section in the MIC261201 datasheet for more
information.
