Most of you will be familiar with using a 7805 5V voltage regulator. It is very simple; connect the +9V from the battery to the left hand pin, ground the middle pin, and the right hand is +5V.

[Alex Eisenhut] needed to replace some old TO-3 voltage regulators ... These three pin metal cans were very common, especially the LM340 5V regulator which was, of course, a linear regulator.

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).

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 ...
