Linear Power Supplies

A linear power supply features a transient response time up to 100 times faster than its switch-mode counterpart, which is important in certain specialized areas. Because the size of the transformer is directly proportional to the frequency of operation, a linear power supply is larger and heavier than a switch-mode power supply. A switch-mode power supply can generate high-frequency noise that can interfere with electronic equipment, making a linear power supply a better choice for powering sensitive analog circuitry.
