In this video I'll talk about some of the things you need to watch out for when designing a power supply for low power applications - specifically low quiescent current draw. I'll test three common linear regulators and show you what the current draw is when no load is attached. Just a quick one here to hopefully help you choose the right supply for the job. We can get into other things with power supplies as well and show off some nice DC-DC switch mode regulators as well.
