Low Voltage Power Supplies II - Linear Regulators

Bart Greene, PE

Voltage regulators are a mechanism for providing a fixed DC voltage that does not vary from its nominal value under changing conditions of the input to the regulator and the load drawn from the regulator. Linear voltage regulators are one of the two major types of regulators; linear and switching. They can be found in many of the electronic devices found in the home and work place.

This course is the second in a three part series about Low Voltage Power Supplies. The first part, Linear Voltage Power Supplies I, was an overview of DC power supply designs and architectures. Linear voltage regulators were introduced and discussed at a very high level. This course goes into detail about design considerations and the operation of linear voltage regulators. Principles of operation are explained in detail and insight into their design is presented. The course includes the design of a linear voltage regulator from discrete components and how integrated circuits can be used to replace major functions. The design of high current voltage regulators using multiple low current regulators is presented. The audience should be familiar with principles of transistors and circuit theory to effectively use the material presented.

After completing this course and the previous course in the series, Low Voltage Power Supplies I, the attendees should be able to design a basic fixed, low voltage, regulated power supply. The audience should also be able to understand how to select commercial power supplies for a particular application.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
