While they are slightly dated, linear power supplies are still widely used for a variety of different applications, and the reason is that they can actually be quite beneficial while still operating at a high efficiency.
What Is It?
A linear power supply, also called a linear regulator, functions by dropping the excess voltage to convert an inconsistent DC voltage into something more constant and often lower.
Linear regulators regulate output, and an output that remains constant is often required for many different applications.
What Are the Benefits of Using This?
There are some benefits to using a linear power supply, which at one point was standard almost everywhere.
* The design is very simple
* A small number of components allow for easy manufacturing, usage, and repair.
* For that reason, they are typically more reliable. Fewer pieces equal less room for error and malfunctions.
* A linear power supply is often noted for its lack of sound or, at least, significant sound. They typically operate very quietly. There are plenty of environments where a low level of noise could be useful or even necessary.
* They are also cost effective and low maintenance.
Applications of Linear Regulators
You can use a linear power supply for a variety of things, and considering the previously mentioned noise levels, it could be your best option for a sensitive area. Other than that, it can be used for all of the following, and even more.
* Anywhere a low level of noise would be required
* Signal processing
* Sensors, converters, and certain circuits necessary for data acquisition
* Testing equipment, both automatic and for laboratories
* Control circuits
There are many different linear regulator products available, and it’s all about finding the one that best suits the application.
