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.

Not really sure what the purpose of that resistor is. I’m trying to get my Universal power supply working. Let’s keep KISS principle LM System Power Management and.

If you need the special specification product, please contact our service member by telephone presented daatsheet shortform cover or e-mail to: I never understood why the circuit was set up like that, but that makes sense.

I can’t explain what the purpose of the resistor is, but I remember on my Sprint 2 it was very important that the resistor be within specs or the voltage would not be correct. Learned something new today.

I tested and used the same freq offset and works. It will not heat that much 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.

Physics fall Exam 1: I think you made a confusion 1A 0. Power supply 5v regulator – what’s wrong with this picture? Log-In Get access to additional features and goodies. Most likely its either to balance output impedance or current limit the regulator.

It is not a shortcut,I think you exagerate CC pin is on D2. I would love an explanation of what that resistor is supposed to do the datasheet for the 78H05 regulator doesn’t have such a resistor in the sample circuit.

This is due to the PCB having a 78H05 linear regulator on it which disipates the difference between a 3S lipo down to 5volts. Recommend This Article You need to log-in to rate articles. LTC – Linear Technology. Looking for your store account? Originally Posted by midelic. Thanks for the explanation. Even more so, can anyone tell from this circuit what might be wrong with my PS?

If I disconnect the resistor, the output is 5.

May 19, So initially I thought the regulator was bad, but I got a new one and the same 788h05 is happening. In using them however you may notice it gets rather warm after a few minutes use, and even more so in sunlight. Originally Posted by datashete You make confusion input current with output current.


Be careful the diagram there is different Tested by minimal Vin and constant resistive load.

What I would do is pull up the regulator and solder in a little sBEC. Are you sure your rx is set datashest frsky 2 way not one way? There are bigger fish to fry here. Anyway you can put whatever you want there are only pads on the board.

Did you test Frsky protocol? Operation under no load will not damage these devices, however they may not meet all specifications. Word Pro – MIW Leave 3, 6, 7, and 8 floating.

Might have already been said, but LDO supplies need a minimum load to regulate.
