Trying to regulate 5v from 7.4v
January 21, 2011
I have a LM2930S-5.0:
in this mess:
I have a cap across the input and a resistor in line on the output (it was 6.8 before I added the resistor).
Yes, it is a cheap meter, but measuring VCC on a Mega I get 5v and on a Fio 3.3v. It is reasonably accurate.
What am I doing wrong? I don't want to smoke my 5v uC. The VR should be putting out 5v (datasheet says 5.5v max).
