#105909 - thank u kai i am already having
Responding to: ???'s previous message

Sorry for my languange i am new to this forum. slowly i will learn all rules.

I am already using a big capacitor and a good transformer(3A rating written on it). my ckt is drawing below 100mA.
and I think grounding is proper.

I donot have a CRO in my home. but i am planning to have one.

do i need some sort of line conditioning or line surge protection.

one more problem was added today on the same ckt board i have 24c02 serial eeprom when i was testing my ckt for the voltage fluctuation problem the 24c02 was also written my AAh ,55h randomly in the chip.

I think the voltage and current spike and transients due to switching loads are reaching to the ckt.

I will wait for reply.
thanks i really love this forum
