Editor's note: Designers at all levels of power management design will find this application article both educational for those not very familiar with these basic concepts as well as an excellent ...

(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) The linear voltage regulator was introduced in Part 11 of this series (link below).

Among regulators, the simplest regulator circuit is for a low-dropout (LDO) voltage regulator whose topology is shown in Fig. 1. As a linear voltage regulator, its ...

People have been predicting the demise of low-drop-out linear regulators in cars for many years. Yet low-drop-out (LDO) regulators continue to survive and even thrive because they're cheap and easy to ...

A low-dropout (LDO) regulator is a simple, inexpensive way to generate a regulated output voltage from a higher-voltage input. It’s inherently low-noise because it has no switching transients, and it ...
