no that would be find to run the ping sensor with out the caps. but if you did use the caps then you could make a 5 v. break out because most of the other sensors will be looking for 5v. so you may can use it to power other such devices.

Hey guys...

I use this setup, but there's hardly and light coming from lights I wired up. (Yes they do light up on 5V from another battery pack) Direct to the battery the lights are bright as day. Going from my science homework, do I need a resistor or something before the power enters the regulator?

Any ideas?

Use a voltmeter and measure the input and output voltages.

1V! I'm not sure why they there not regulating 5V! Amperage is 0.05 on output.

Here's a link to where I was told to use LM1084's. DJ in second post. YAY or NAY for these regulators

Here's what I just got on ebay. They're small so they don't take up much room, input 4.75 to 20 vdc, output 1 to 17 vdc @ 1.8 amps.

Thanks, but I want to figure out why these don't work. I found that the regulator has an ADJ mark on it, though the regulator on the ez-b v3 has a 5.0 mark instead. Could this be I got the wrong one?

Sounds like maybe you got something like a NTE1929 by mistake. They look about the same. I ordered an LM1084 from an ebay seller and wound up getting a TIP310C transistor instead. It was only like $1 so I didn't bother trying to return it.

These definitely look like lm1084s...
