The 78XX series of regulators are very handy to use. If you need, say, a 5V regulator, you grab a 7805, add a capacitor for stability, and send in enough voltage for the regulator to work with.

These three pin metal cans were very common, especially the LM340 5V regulator which was, of course, a linear regulator. Today, you are more likely to see a 7805 in a TO-220 case or something ...

Based on UMC 0.18um 3.3v/1.8v Logic Process, current design of Power Regulator is to provide the 3.3v voltage output regulated from a 5v input supply. Moreover, the design is resilient against any ...
