An adjustable voltage regulator is a type of voltage regulator IC whose regulated o/p voltage can be changed over a range. So there are two variations of the same like positive adjustable voltage regulator & negative adjustable regulator. The positive adjustable voltage regulator example is LM317. Similarly, the negative adjustable voltage regulator example is LM337, the complement of LM317 IC. An adjustable voltage regulator IC generates a DC output voltage. It can be changed to any other … [Read more...]

The fixed output voltage regulator is an integrated circuit from the LM78xx series. This series mainly includes LM7805, LM7812, LM7824, LM7809, etc. So these regulators are frequently used in electronic circuits to provide a stable output voltage for different input voltages. The term 78 in this series of regulators signifies a positive voltage regulator whereas the remaining number indicates the output voltage provided by the IC. But these ICs suffer from huge heat loss, thus a Heat sink is … [Read more...]
