When designing a powered device, the question sometimes arises of whether a Linear Voltage Regulator or a Switching Regulator is more suitable for the design. Understanding the differences between the two can help you make the right choice for your application. [regulator] Linear Voltage Reg…

The symbol itself is a symbol for a Varistor in Scheme-it [image] Basically in the diagram he is showing a variable impedance. This could also be shown with a potentiometer or variable resistor.

yeah that’s what i thought, but the diagram looks more like a divider than a regulator.

Hello @periquita , The switching frequency is usually way too low to affect 2.4GHz for your bluetooth. Analog Devices had a good article that talked about Switching Regulator noise. It may help to clarify. https://www.analog.com/en/technical-articles/comprehensively-understand-and-analyze-switchin…

It technically would be a divider. This is probably the simplest way to express what a regulator is. I know from practice regulators are a little more…complex.

I got that the Switching regulator has better efficiency but what about the noise? I’m working with Bluetooth and NFC will be interference?
