It can supply of 5 volts as well. I hope also this guide to be useful for you. I have seen this voltage regulator circuit duplicated many times, but with different values for the smoothing capacitors.

Can you tell me what kind of problems? The Mega has an external power source detector. Quickly find another product in this range by Output Voltage: Designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

Using an external 5volt source could introduce other problems.

The circuit will work without the extra components, but for reverse polarity protectiona 1N diode is provided at the input, extra smoothing being provided by CuF 50V. Can’t you feed the Mega from 12volt. Many electronics circuits and projects for learning in 78s055 ways.


And few parts 78d05 in a circuit, is high-quality and low noise. I always knew that it was dangerous, and Qdeathstar wrote that his computer got damaged. Input voltage of 78S05 is 12V.

ST L78S05CV +5V 2A Voltage Regulator

Alternatively use our Quotation page. Avoid if you can. Does this require a heat sink and if so please can you suggest a suitable one? That circuit does not work anymore if you feed 5volt directly into the 5volt pin. The Ethernet Shield will be powered by the 5V of the Mega board. Javascript is currently disabled in your browser, please turn it on to avoid loss of functionality. That should prevent most trouble, but it is not known how any random computer will behave when 5V is powered to the USB.

Next Post Dual adjustable power supply circuit diagram using and Fixed voltage regulator from the ST 78S series.

Then, I choose this circuit for him. Larger for ripple, smaller for noise.

In model to be simple, use little equipment, build easy. Or use universal PCB Board that difficult. The W gets hot and requires a lot 78s5, the newer W might be better, but not yet supported here at Arduino. When you apply 5V to the 5V pin, current might flow into the computer. Qdeathstar 780s5 Member Posts: If you use 7. The four different types of cookies are: In the datasheet, max.

If you are using the full 2 amps then a heatsink is required we recommend The heat created by the 78S05 will be limited if you use 78s005 same 7. Have a look here.

If you do not want to design own PCB. Wawa is right of 780s5, you certainly are going to connect that USB cable some day, because the sketch needs to be altered and updated. The question is about 78S
