If your project's power source isn't suitable for the development board or components you plan to use it with, a regulator or buck converter can help you reduce that down to the voltage you need, which for makers is commonly 3.3V, 5V or 12V.

We offer a wide range of voltage regulators and buck converters, each offering different output currents with a range of additional features available such as adjustable output, boost functionality and popular connector ecosystems.
