Hello
I need to power a bunch of circuits that ask for 3v and 4.5v and I'm thinking to built a simple circuit using two LM317's and powering it with a 9v power supply..
Would heat be an issue? Do I need heat sinks?
Is there a cleverer way of powering down from 9v to 3v and 4.5v?
Everything is DC BTW..
