We’re quite sure that all hobbyists have used the 7805 voltage regulator at least once in their lives. They are a simple way to regulate 7V+ voltages to the 5V that some of our low power ...

[Alex Eisenhut] needed to replace some old TO-3 voltage regulators and decided ... especially the LM340 5V regulator which was, of course, a linear regulator. Today, you are more likely to see ...

The present IP is a voltage regulator to generate 2.5v power for on chip circuits. Normally, its power supply is 4.5v~5.5v. The generated power voltage is 2.5v (2.25v ~ 2.75v).
