For an automotive project i am using a custom 328p project running at 5v. For this i use a voltage regulator to convert the 12-15v down. On my breadboard prototype i use a lm7805. Now i'm thinking about going SMD, i've ordered some lm1117-adj. I should be able to solder a sot-223 by hand. I choose a batch of -adj so i can get any voltage i need in future projects.
But now i also saw other types of regulators, eg. Mic5205. I'm now confused whether i ordered the right parts, there are so many regulators available! Can you help me please?
