Most people don't even use input power regulators. 5V wall warts are dirt cheap due to USB charging and provide the exact voltage you need. Why mess around wit

Why mess around with a 7805 when you already have a dozen 5V power supplies lying around the house?
- arcticbull 4y agoUnless it's a USB power adapter - which is a good choice, btw - I'd be very wary about what's coming out of that 5V no-name wall wart. That power can look like ass and not be close to 5V. If you're doing that an LDO isn't a bad choice.
