Linear and Switching Voltage Regulator Circuits

This chapter delves into the fundamental concepts of linear and switching voltage regulator circuits, crucial components in electronic systems, including those used in ham radio. It begins by discussing the characteristics of linear voltage regulators, which adjust the conduction of a control element to maintain a constant output voltage, and contrasts this with the operating principles of switching regulators, known for their efficiency achieved through rapid on-off control of a control device. The chapter further explores specific components like Zener diodes used as stable reference voltages in linear regulators, the efficiency and application scenarios of series and shunt regulators, and the importance of remote sensing for accurate voltage regulation. Additionally, it covers the integrated design of three-terminal regulators and the primary categories of electronic voltage regulators, providing insights into their functionalities, applications, and the critical factors influencing their selection in various electronic designs. Understanding these concepts is vital for anyone involved in electronic circuit design or troubleshooting, offering the knowledge necessary to choose and implement the appropriate voltage regulation solutions.
