How to Select a Power Supply - The Byte Sized Engineer | DigiKey

Whether it’s a battery, an AC power adapter, or voltage regulator, there are a lot of options to choose from when picking a power supply for your project. This video will help clarify what each of those options are and help you pick the right one for your project.

Thank you !

Linear regulators dissipate power depending on current draw as well as voltage drop. So if your device consumed 1mA, then the 5V regulator, supplied by a 12V battery will be dissipating 7mW.
Milliwatts, folks. Sure it's more than the 5mW of the device but it's not an inferno!
A switchmode power supply may infeed be less efficient at such low current and make significant electrical noise.
