"If I have understood these sentenses correctly, they want to say that LDO type regulators, being having low drop out, will dissipate less power than normal linear regulators.

In fact, an LDO will dissipate the same amount of power on a given voltage difference and load current as that of a normal type requlator."


Exactly! That is what I told Andy in this post. The key word my other post you quoted is: allows. By this I meant to say that it is possible to have lower power dissipation with a LDO, because it can operate with a lower input voltage. Perhaps I should have made this more clear.


"It is impossible for a linear regulator to dissipate almost 13 watts continuously without heating up."

A fact already noted by Hans van Pelt and myself :o).


Best regards,
