L7805 three terminal positive regulators are available in the TO-220 package and with 5V output voltage.If adequate heat sinking is provided, they can deliver over 1A output current.
I bought just 2 of this regulator from this site on 16.09.2014.
Among them one gives 4.3 volts on it's output.
Another gives nothing(it's dead).
I know what I am saying....
So, please check your lot.
I think you will get some clues...

We are sorry for this inconvenience. Please send us the ICs back along with a copy of the invoice. We will check those and give you a replacement.

It's ok.
I have already disposed them of.
Actually returning is not a solution. It really eats up a lot of time buying things online. Returning will eat some more.
So I bought some from the local market.

what is the minimum input voltage??
Akashrayhan | May 18,2016 at 07:48 PM
And what is the maximum input voltage ??

The maximum input voltage of a "Voltage regulator IC LM7805" is about 40V. But maximum 35V input voltage with proper heat sink is recommended by us.

I get maximum 4.6 volts output.
But I bought another from local shop, that gives 5 more volts output.
FAHIM_REAZA | Jun 19,2016 at 09:32 AM
Please make sure that, the input voltage is greater than 7V.

Do you have the heat sink that can be used with it?
