I need to convert 12 V down to 5 V and 3.3 V.
I am using linear regulators right now but they get pretty warm and eventually I would like to supply more current for it (around 500-700 mA).
If I used a buck converter to get the voltage down to 5 V, then also feed the 5 V into the 3.3 V linear regulator is that acceptable? Assuming the buck converter can handle the current of the 5 V components and the 3.3 V ones? Also, this would cut down on heat from the linear regulator, correct?
