Hi,
I am designing a 19' inch rack system. A Switch mode PSU offering 5V, +/-12V has been selected. I am using the 5V supply to generate a 3.3V supply for a micro and DAC. The 5V will also supply the +ve supply for a 0P1177 opamp. What filtering would I need for the 5V output from the PSU. Would a 100uF low ESR cap + 100nF ceramic do. I was also thinking of a PI filter too.
Thanks in advance.
Best regards,
Rajinder
