problem with 5v regulator
« on: March 19, 2009, 01:25:58 AM »
Hi,
it looks like my 5v regulator from $50 robots doesn't work.
I have connected my battery to it, and I have uncontrolled voltage to my servos (which is fine) and zero volt to my circuit.
How can I check if it's working correctly?

Thanks

I had the same problem

Check your connections to the regulator, if it's getting unusually hot you've got it wrong.

I'm pretty much sure that I have connected it the right way, but will double check today.
Also, I'm using common ground.
Regulator isn't hot at all.
And I have connected the battery correctly, I double checked that.

Will give it a try tonight, and if unsuccessful will post a photo.

Thanks for helping!

use a multimeter on the legs of the regulator

I had a problem of the regulator getting very hot. I checked all my connections, I mean ALL of them, every wire, capacitor and everything and I finally got it working, but never used it, didn't have all the features I wanted.

also, if the problem persists, do some continuity tests to make sure all of the soldering is good.

false alarm.  :-[
double checked right now - all is working fine.
except that my diode stopped working. :) but that is easier to fix.
