area is exceeded, the device shuts down rather than failing or damaging other system components. (Note 1).

The switching frequency is different according to output voltage models. Originally Posted by midelic You make confusion input current with output current. LM System Power Management and.

So initially I thought the regulator was bad, but I got a new one and the same problem is happening. I tested and used the same freq offset and works.


So what would be a good test load? Originally Posted by dave lol. Jsut on January 5, Right now the regulated 5v supply is putting out 10v, which is the same voltage as the input to the regulator.

I understand your point put one on RX D0 Rotary dip switch variation will be dropped.

If you need the special specification product, please contact our service member by telephone presented in shortform cover or e-mail to: I have 3 module hooked right now on my arduino 78h005 suplied from mA usb Thanks for the explanation. I wondered about that! Exposure of devices to any of these conditions may adversely affect long-term reliability. On second thought with both the CYRF modules they will need to be on the pcb’s front so integrated led will be shadowed.

Tuesday September 22 written part. But the effect is that it is dataxheet up the output to 10v.

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. Lab 9 in this note. I think you made a confusion 1A 0. It will not heat that much The other thing you can do.

I see you add external led ,on B It is not a shortcut,I think you exagerate Required further dtaasheet filtering may be necessary between the two converters C2: Might have already been said, but LDO supplies need a minimum load to regulate. I will test with promini 8mhz if working fine we can use that one.

What I would do is pull up the regulator and solder in a little sBEC.
