Hello,

I have regulator circuit with LT763 for regulating from 7.4V to 5V. Input and output signal has 60Hz sine wave like the attached file. So why is this problem happen? How can I solve it?

Hi,

Maybe no circuit problem, but a measurement problem....

Hi,

When is the next piece of the puzzle available? Should we tune in next week for a sneak preview of your actual circuit schematic or just pointlessly guess until then? ;)

Apart from what Klaus said, which I assume was for a reason...
Is Vin a sine wave? If so, is shutdown tied to Vin?
Have you respected datasheet guidelines about capacitance needed or not needed for stable operation?

Thank you very much for your response! Yes, it was a measurement issue and I fixed the connections. Then problem was solved.
