Can I Increase Current Output to 500mA with a 7805 IC and Capacitor?

[neeraj kaira]

Hello everyone.
I'm having 5v,100 mA current in the rectified output. I used a 7805 ic to regulate the voltage and a pair of capacitor as filters. And my question is i want 500 mA current in the output keeping 5v constant. Is that possible? Any circuit to increase the current?
Thank you hope somebody will help...

You need to provide more info. The current in the rectified output as you state it is dependent on the load and the ability of the source to provide said current.

You could reduce the load, add another power source, or redesign the circuit if you have sufficient input power.

I used a stepdown transformer giving 19 v.

Can you provide a circuit. Please its my minor project

V=IR

If you want bigger I, but the same V, what do you need to do?
Details are important - perhaps you are attempting something like this:

Thank you sir :)

Depends on the current rating capabilty of the transformer and recitifiers. If they can handle it then you just need a properly designed 7805 with proper heatsinking. You may need to add bypass capacitance to reduce increased ripple.
What you need to replace depends on the capability of the components you have already. There is no way I can determine that without a schematic and datasheets.

Which type of stepdown transformer should i use so as to have maximum current.

 

[meBigGuy]

It just has to be rated (have low enough resistance) to handle the current.

Hmmm thanks brother
