Arduino LED driver usage

I try to use my Arduino Uno for managing 16 RGB LEDs therefore I want to use a breakout board for a PCA9685. It needs 5V and the Arduino has a Pin with 5V now I didn't find some specification how much mA it delivers? For the LEDs i need 16 x 20mA I think?

But im an absolute Newbe in electronic area. Wich topic should I read to learn it by myself?
