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 ...

Low dropout voltage regulators (LDOs) are common in many applications. State of the art Power-Management Integrated Circuits (PMICs) for smartphones and other portable devices include over a dozen ...

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 ...

Linear voltage regulators are key components in any power-management system that requires a stable and ripple-free power supply. A subset of linear voltage regulators is a class of circuits known as ...

Although the LDO regulator is often one of the least costly components in any given system, it is often one of the most valuable components from a cost/benefit basis. In addition to output voltage ...

The following tutorial nugget comes courtesy of Greg Waterfall of Texas Instruments, one of our experts. In the low-dropout (LDO) regulator, the pass element (Figure 1) can be a single PNP bipolar ...
