5v voltage regulator
February 26, 2010
I'm using 5v regulator (this one:http://solarbotics.com/products/lm2937/) and it doesn't seem to be working correctly. I'm under the impression that this is how it should work:
- On the first of the three prongs, I put the positive (red) wire from a 9v battery port thing
- In the middle prong, I put both negative (black) wires.
- On the third prong, I put another red wire
- A black wire from the middle prong and the red wire from the third prong should, when attached to voltmeter, give 5v. Currently it is giving 9v. I have tried switching the positive wires.
Am I incorrect in any of these assumptions? If not, what am I doing wrong? Basically, how do I get 5v from 9v?
