An IC can be either an analog device or a digital device. Today, in early 2014,
I think it's accurate to say that the vast majority of integrated circuits being
manufactured and installed in electronic things now are digital.
Both. An IC (integrated Circuit) is a compact form of several electronic circuits. These circuits may be analog or digital.

LM7805 is not a microcontroller. LM7805 is an +5.0V 1A voltage regulator.
One can find in a mixed signal integrated circuit having both analog circuits and digital circuits. One can also purchase a book from Amazon explaining in more detail.
Data regeneration is not possible in analog circuits.Signals has degeneration and distortion so it causes noise.But in digital circuit signals are quantizated and regenerated even if they had corruption.
Analog circuit continuous uses the time voltage and currents while digital circuits are sometimes called the on/off and high/low control of voltage in circuits.
If you are referring to Ladder network in digital circuit or digital to analog conversion the ladder means cascading of component which are R-2R ladder circuit from conversion of analog to digital. it is used for obtaining the low value of resistance.
Integrated circuits are produced with a myriad of functions today. Although early ICs tended to be digital logic circuits, there have been both analog and digital types throughout their history. Many ICs now combine digital and analog circuitry within a single package. So, an IC can be digital, analog or a hybrid of the two.

Basically an analog circuit is any circuit which uses the voltage (or current) level to deliver information (say.. a sine wave or an audio output). In contrast a digital circuit would only use a high and a low voltages (square wave, binary data transfer etc). Discrete circuits are circuits only using basic components (resistors, transistors, capacitors etc) instead of integrated circuit packages. A lot of discrete circuits are analog but they don't have to be. And a lot of ICs are digital but they don't have to be...

Digital data requires less bandwidth than analog data (e.g. new digital television broadcast compared to old analog broadcast), so more data can fit in the same frequency (e.g. DSL compared to analog modems). This is the primary advantage, although it is also generally stated that data is easier to recover and more tolerant towards interference.
