area is exceeded, the device shuts down rather than failing or damaging other system components. (Note 1). This feature eliminates costly output circuitry. 78H05 Datasheet, 78H05 PDF, 5-Volt 5-Amp Voltage Regulators. ing a continous load current in excess of 5 amperes at a nominal regulated output voltage of 5 volts. The 78H05A has built-in protection.

Jsut on January 5, CC pin is on D2. These components should be mounted as close as possible to the module; and all leads should be minimized to decrease radiated noise.

Datasheeets & Application Notes

So the external one is needed. Tuesday September 22 written part.

Page 13 of First. What I would do is pull up the regulator and 7805 in a little sBEC. Posting Quick Reply – Please Wait.

Measured Input reflected ripple current with a simulated source inductance of 12uH. Lab 9 in this note.

Selling 78H02, 78H05(5A), 78H05K with 78H02, 78H05(5A), 78H05K Datasheet PDF of these parts.

That resistor basically bypasses the regulator. Be careful the diagram there is different The receiver module needs 5V. Right now the regulated 5v supply is putting out 10v, which is the same voltage as the input to the regulator.


The information and specifications contained in this data sheet are believed to be correct at time of publication. Even more so, can anyone tell from this circuit what might be wrong with my PS?

Because per this page PB, if I’m not mistaken, doesn’t use it on the modules. You need to log-in to comment on articles. Return to DIY Electronics.

I see you add external led ,on B If I disconnect the resistor, the output is 5.

5.8ghz Reciever heatsink

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. Do not operate the unit s exceeding the absolute maximum rating, over rating causes damage 78h0 the units.

I touched many times. What would be a good test load so I don’t have to risk my board? I wondered about that!

I have 3 module hooked right now on my arduino promini suplied from mA usb Can you post a pic with your connections?

A minimum load of 10mA is recommended. It will not heat that much That would make it 2. Originally Posted by midelic You make confusion input current with output current.

Maybe an R off of a g07 chassis 2 ohm, 7 watt? Anyway you can put whatever you want there are only pads on the board. Log In to reply. Last solution is to send me one of your CC chip May 19, ,
