What are the Advantages and disadvantages of IC voltage regulator?

IC voltage regulator performs better than any analog voltage regulator.

Some IC regulators IC no. are given below-

Positive IC voltage regulator- 78xx

Negative IC voltage regulator-79xx

where xx varies according to the use of ICs raring.

as 7805 gives the positive 5 Volt & 7905 gives the negative 5 volt.
