APPLICATION NOTE
A NEW GENERATION OF VERY LOW DROP
VOLTAGE REGULATORS
by Riccardo Erckert


Monolithic voltage regulators have become a standard device of modern electronics. Most of to-
day’s PC-board designers tend to use them just like transistors or resistors. In reality these versatile
devices have a quite complex internal structure. So some basic rules should be respected for their
application.


1. A LITTLE BIT OF HISTORY using an darlington output transistor consisting of
