Place both at the power pins. I don't know what you mean by the "output" side. Both go on the power pins. Try googling power supply byapss or power supply decoupling for more information.

Oh, and place the caps as close as possible to the power pins. Especially the .1uF cap.

I mean at the output of 7805 and 7812 I have placed 0.1uf. should I place 10uf also at output side??

 

Put a 10μF electrolytic capacitor at the output of the regulator

AND

a 0.1μF capacitor at the mcu power and GND pins

AND

a 10μF electrolytic capacitor at the mcu power and GND pins.

Keep all leads as short as possible.

but as per datasheet they have said. 33uf(I have placed 1uf) at 7805 input side and 0.1uf at output side.

 

Please read link in my sigline about Bypass caps, Read Me!

It has links to show the effect of having capacitors further away from the point of use.

Always use an electrolytic (I use 22uF since they have low ESR compared to 10uF), and a 0.1uF Ceramic in parallel, across the V+ and GND pins of all ICs

Not doing so will result in... The glitches you are seeing....

 

thank u all...
