(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 ...

The switching-versus-linear regulators debate is rather like ac versus dc power. Most people take it to be about which is best, and that has been decided, so discussion over. The traditional, widely ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...
