I am sorry but what do you mean?

So initially I thought the regulator was bad, but I got a new one and the same problem is happening. I never understood why the circuit was set up like that, but that makes sense.

Measured Input reflected ripple current with a simulated source inductance of 12uH. You make confusion input current with output current.

Because per this page PB, if I’m not mistaken, doesn’t use it on the modules. If you need the special specification product, please contact our service member by telephone presented in shortform cover or e-mail to: So the external one is needed.

The other thing you can do.

If I remember my wattage equation, that would be I’m trying to get my Universal power supply working. Last edited by midelic; May 19, at The Sprint 2 board uses an Lm for a voltage regulator.

Recommend This Article You need to log-in to rate dataeheet.

But the effect is that it is pulling up the output to 10v. Thanks for the explanation. I’ve seen them used as bleeders across big filter caps, but not usually that low of a resistance. The receiver module needs 5V.

Bear in datashet I do not have this connected to my mr do board I don’t want to fry it with 10v! Originally Posted by midelic You make confusion input current with output current.

That resistor basically bypasses the regulator. All dimensions are typical in millimeters inches. You will just need a thin piece of copper cut to size 10mm wide x 25mm long, a pair of long nosed pliers to bend it into shape.

Seems kinda screwy to me, though I’m sure that circuit diagram is correct in that regard. Lab 9 in this note. You need to log-in to rate articles. Originally Posted by midelic I think you made a confusion 1A 0.

Anyway you can put whatever you want there are only pads on the board.

Tested by minimal Vin and constant resistive load. I have 3 module hooked right now on my arduino promini suplied from mA usb Page 13 of First. Originally Posted by dave lol.

I used it on my module and I had no problem heating or otherwise. No rights under any patent accompany the sale of any such product s or information contained herein. Devices are filled up with flame retardant resin.
