Hello,
I'm wondering if there is any advantage on using a separate regulator for the Vccaux.
I already have 2.5V generated on the board by a switching regulator for the multiple DDR chips and for some Vccio of the spartan 3. Now, with the new TI regulator that has 3 regulators in a chip, I can have a separate LDO to power just the Vccaux portion. Is it useful to have it separate ?
Thanks,
Sylvain
