Learned something new today.

The shunt resistor provides extra current beyond with the regulator can supply. Anyway you can put whatever you want there are only pads on the board. I would love an explanation of what that resistor is supposed to do the datasheet datasheey the 78H05 regulator doesn’t have such a resistor in the sample circuit.

I tried a coin door lamp and that pulled it down to a little more than 9v, but obviously not enough of a load. So initially I thought the regulator was bad, but I got a new one and the same problem is happening. Right now the regulated 5v supply is datawheet out 10v, which is the same voltage as the input to the regulator.

I assume the same explanation applies to datashert Atari circuit in the Sprint 2 example I posted above? I will test with promini 8mhz if working fine we can use that one.

I’ll put on first post. Documents Flashcards Grammar checker.

Measured Input reflected ripple current with a simulated source inductance of 12uH. Its pulling your voltage up to 10v because you have no load. Are datasheef sure your rx is set to frsky 2 way not one way? The other thing you can do.

I used it on my module and I had no problem heating or otherwise. Pin to case tolerance: That would make it 2. Once bent to a ‘L’ shape, you should tin the short side of the copper so it is ready to solder onto the PCB, and also tin the PCB aswell.

Be careful the diagram there is different Remember Me Forgot Password? Recommend This Article You need to log-in to rate articles. 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.

If I remember my wattage equation, that would be I wondered about that! A minimum load of 10mA is recommended. Can you post a pic with your connections? I touched many times. I’ve seen them used as bleeders across big filter caps, but not usually that low of a resistance. It is not a shortcut,I think you exagerate I don’t know why it’s wired in his MultiModule.

These components should be mounted as close as possible to the module; and all leads should be minimized to decrease radiated noise. Thanks for the explanation.
