I'm looking at this IC:

   http://ww1.microchip.com/downloads/en/DeviceDoc/20001984g.pdflink here

And noticed under "typical application" a simple circuit diagram. What is the purpose of the capacitor that connects vinVin directly to ground?

How does this affect the current/voltage being applied to vdd and the LED?

I have virtually no understanding of how/why capacitors are used in general. My very limited electronics experience has just about covered resistors. Would appreciate small words, and possibly somewhere to get further information (free online courses?)

thanks
