Hey everyone,
I'm pretty new to electronics. so, be easy. I've taken most fundamentals course and have a good understanding, but I'm very limited on practice and experience. I learn best by experience, so I am doing things and trying to apply them to my book learning.
So, I am working on a project that requires 5 volts, at about 1-1.2A. My source is coming in as 12V. This is a hard requirement. On my breadboard, I am using a standard 7805. After my load is 100-150mA (sustained) my 7085 gets VERY hot. I understand why this is, but in the end my load is going to potentiall be 1.2A. the 7805 is rated for this but the package size I am intending cannot possibly handle the 10lb heat sink I would need on this
Anyway, I am looking for advice.. there has to be a better way. I want to take 12V to 5V, at 1.2A without creating a fireball. Any other suggestions?
Thanks so much!
