Capacitors minimum value
Usually when an LDO circuit recommends a minimum value of a decoupling capacitor to ground, a larger one will do.

However, an LDO is a surprisingly difficult thing to design well, and maintain stability, into whatever the unknown customer is going to throw at it. The designers might have assumed requirements on the circuit that are not obvious. 

The now well-known 'ceramic versus tantalum ESR' issues with LDOs are a case in point. A larger tantalum capacitor will usually have a lower ESR than a smaller one, and so breach the minimum ESR requirements, even if the capacitance is OK. Older LDOs required a nominal ESR, but newer ones can work with ESR right down to zero, the data sheet will tell you which.

Always read the data sheet carefully to understand whether component values are nominals, minimums or maximums. It's the only way the designer of the component has for talking to you, to get you to provide the electrical environment that he has designed the part to work in.

Just because you see a circuit working OK on youtube does not mean that's a good way to use it, there may be other features of that particular circuit that aren't apparent to you as a viewer. The original IC designer will have tested his circuit over extremes of temperature and process variation, the one you see working may be an unusual example.
