Hi Bheema,

Surprising to see that your power supply design is a linear device; transformer and linear regulator. This is really old techology and will make your system perform poor. There is only benefit with your design. It is simple to design, but that should be no argument anymore these days. There are plenty off the shelve products and designs efficient switching power supplies.
