| * Voltage regulators — Buck (step-down) converters convert a higher voltage to a lower. Boost (step-up) converters convert from lower to higher. Switching regulators are often more efficient than linear regulators, but might be noisier. Don’t step down too much voltage when using a linear regulator because they get hot. With switching regulators pay careful attention to board layouts (copy them from the datasheet). | * Voltage regulators — Buck (step-down) converters convert a higher voltage to a lower.
