I think your articles have been written by someone who is not a native English-speaker.
Might or might not be catastrophic for the load. The error signal from the bandgap reference is amplified by the error amplifier orange. And what exactly happens if one regulator is inevitably a little higher in voltage than daatasheet other? Home Questions Tags Users Unanswered. Another one And another Sign up using Facebook. With two voltage lm7805 in parallel, one might want to naturally produce 4.
A switcher would probably be a better solution. IgnacioVazquez-Abrams there are dozens of options from different manufacturers and the datasheets are all different.
This amplified signal controls datasheett output transistor through Q Here’s a decent looking circuit that adds two transistors around a to give significantly more current and short circuit protection: There is also potential of causing one to overheat. This also allows for lower valued resistors. There is no reason to do something unusual, large, expensive and all around klunky, as a linear regulator that dissipates 10 W even with optimal input voltage.
We are all non native english speaking people here. Just keep in mind that the filtered but unregulated input current to the regulator circuit must be greater in amperage than your desired output, in order to maintain regulation, if the input current drops below the set output current, there is no telling what can happen, from circuit damage, to oscillation of the output, which would be the equivalent of feeding 5v AC to your circuit being powered.
The values of capacitors can also be changed slightly. Switch mode supplies seem to have a lot of inertia, and people shy away from them. If it were a good design it would use a switching regulator or perhaps an Pm7085 linear if extreme precision is required for a specific part of the circuit.
IC 7805 (Voltage Regulator IC)
It’s best to use a larger regulator with higher capability. You can’t assume there can be two exactly identical chips. Why not use the high current schematic the datashedt provides? Not all show that wiring.

I have 78M05 IC in D pak package. TI, in current literature says they “employ internal current-limiting, thermal shutdown and safe-area compensation, making them essentially indestructible. The smallest difference between them can lead to problems, and they have to behave exactly the same across the whole temperature range.
Yes you can, however, you need to isolate them from each other which will lower the output by about. The slideshow below also highlights some points with voltage regulators. The greater the difference between the input and output voltage, more the heat generated. Thanks for the ratasheet.
All About IC 7805 | Voltage Regulator
A lot of energy is wasted in the form of heat. If you need that kind of current, linear regulators are usually not the answer, as they will dissipate quite a lot of heat.
Misunderstood 5, 1 5 Capacitors will be beneficial in this case as they are good at maximizing voltage regulation.
