In this course, we will learn about one of the important concepts for any hardware / system designer:  Low dropout regulator (LDO) is a simple and cost-effective voltage regulator to get a regulated output voltage from a higher input voltage. 

Further, we will explore an intuitive approach to managing power and voltage supply for critical analog and digital circuits in mobile devices. We will see what an LDO is, understand how a low drop out voltage regulator works, important characteristics of LDOs and also a few parameters.
