Linear Regulators in a Digital Way (Download)
The linear regulator is a fundamental component in power electronics, designed to convert a higher input voltage into a stable, lower output voltage. These voltage converters behave like a dynamic resistor, which always adjusts to exactly the value that’s necessary to keep a set output voltage constant at a certain current flow.
With all of the easy-to-use, high-efficiency switch-mode power converters on the market, linear regulators are being used less frequently. However, there’s one situation where linear regulators are still very important: filtering the output voltages generated by switching regulators.
