Adjusting the Output Voltage
5 Adjusting the Output Voltage
The output voltage of the Demo board is adjusted to either 5V, 3.3V, 2.5V, or 1.2V by moving jumper J1.
For other voltage options, see the datasheet for adjusting the feedback resistors.
6 Optional Components
The Demo board has many options for input and output filtering. C

5 can installed with
47nF or greater ceramic capacitors to further decrease high frequency noise on the output. Similarly, C
IN
1,
and C
IN
6 can be installed with 47nF capacitors to provide further high frequency bypass for the input
current.
