Linear Power Supplies: Best for applications requiring low noise and precise voltage regulation, such as audio equipment testing or analog circuitry. However, they are less efficient and generate more heat. Often used in low power models and higher power precision power supplies.

Switch Mode Power Supplies: Ideal for higher-power applications where efficiency, size, and weight are critical, but may introduce more noise and ripple, affecting sensitive measurements.

Mixed Mode Power Supplies: Have a switched mode input stage and Linear output stage. Providing a balanced solution, offering both low noise and high efficiency, suitable for a broader range of applications.
