Hi, I'm designing a 5v power supply, this supply will power about 25 TTL chips and 6 seven segment led displays. I am unsure of the transformer's secondary current i'm going to be using a 7805 fixed regulator, i will also provide a metal heat sink for the regulator. Also if any body could tell me where to get an IC that has a digital voltmeter built in it all i would have to do is connect some counters and display the voltage or is there any such IC out there? any help will be greatly appreciated thanks in advance.
