Between the linear and switching voltage regulator. Which is more efficient
Between the linear and switching voltage regulator. Which is more efficient. And in what application can we use both. If you can drop their major differences I'd appreciate. Thanks. @PCB & Analog

Switching is more efficient but noiser than linear regulator. Depending on the application you can choose the type
Switching regulators are more efficient, having efficiency ranging from 70 to 90%+ depending on the topology you're using.
Efficiency of linear regulators can be okay when the input voltage isn't too far from the expected output. Once the input range is wider than the output by a significant amount the efficiency drops, excess voltage are dissipated on the regulator as heat(regulator becomes excessively hot).
So, depending on the application, both can be used.
Linear regulators are simpler regulators that step down the input voltage. The goal is to set the output to a specific DC voltage.
Switching regulators provide much higher efficiencies, but they can be more complex during design, Because it requires more external component
Using a Switching Regulator vs. Linear Regulator for DC-DC Conversion
Do you need a switching regulator vs. linear regulator? Here’s how to bring each type of regulator into your power conversion strategy.
Thanks guys, so if I need more accuracy and efficiency I go for switching.
