batteries?

Batteries don't supply a constant voltage. Most circuits require a constant supply voltage. Ergo, a regulator is required.

 

It’s a generalization. “Batteries don’t supply a constant voltage”, yes. "Requirements for most circuits", yes, but for most devices, no. Therefore, most devices such as usb cards, ethernet cards, ddc, dac etc, can be powered with a voltage in a wider range than as stated as supply voltage. Batteries with voltages that falls within this range therefore work well without a regulator. The reason is that most devices already have built-in regulators, also applies to all motherboards.

You're not making a lot of sense. A regulator internal to the powered device is still a regulator and will be what determines the quality of power supplied to the main circuitry.

 

Yes it’s true. It's often these internal regulators determine the quality of a particular device. But a battery without a regulator can actually be better power supply for a device than the same with one. And provide better SQ. That's the difference I wanted to present.
