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 ...

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 ...

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 ...

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 ...
