Hello, i've recently started with electronics, and i have a question about this circuit:
I wonder if it makes any difference if i switch place of the 10uF capacitor with the 0.1uF capacitor.
It shouldnt make any difference right? I just wanna be 100% sure, so i dont break anything.
Best Regards

Officially, it doesn't make a difference, but for practical purposes it is best to keep the 0.1uF capacitor as close to the regulator as possible, and make sure the connections to the regulator are as short as possible (in wire length).

I doubt the 0.1uF capacitor is needed - its for high-speed decoupling yet the only load is constant, a single LED. If the regulator was suppling a logic chip/circuit then it would be important.

But it also keeps the regulator stable, without it you could get the regulator oscillating. I once had to scrap three thousand set top boxes because the purchase department subistuted a regulator that needed more capacitance than was on the board.

shudder Could they not just add some capacitance to the boards rather than scrapping the units??
What a waste...

No because the cost of rework was high and they would no longer be approved as it wasn't the circuit that was tested at the test house.
You gotta luv bean counters. I suppose the substituted ones where still the correct shade of blue though.

A true 'schematic' diagram, which this one is, is drawn to make it easy to follow the signal flow which is typically from left to right and/or top to bottom. The location of the pins on the components and the components on the diagram are not related to their location on the actual physical device.
A wiring diagram is drawn to make it easy for a non technical person to wire up a circuit. It typically shows a simplified version of the actual devices with the pins in the same order that they are on the component and the components in the same relative positions as they are on the actual physical device.
From this you should be able to ascertain that the typical 'schematic' created by many CAD programs is a bastardized combination of these two concepts and such a diagram is equally poor for both troubleshooting and for construction.
The answer to your question in terms of the 'schematic' diagram is NO. The answer given by Rugged is appropriate when you are actually constructing the circuit. Don't leave out the capacitor for the reasons given by Mike.
