What is the purpose of the LM385 in the Arduino UNO Rev. 3 ? I see one of its output simply feeds a MOSFET (?) while the other lights a LED. Thanks.

UNO Rev. 3: What is the LM358 for ?

The schematics won't show the other pins for the LM358. What powers the IC? Since power source hasn't been selected yet, where does it get its power (5V, I guess) from?
