You CAN achieve both low noise and high efficiency to make your portable or line powered device run better. The tried and true DC/DC followed by an LDO works.

You CAN have both - low noise AND high efficiency

For noise-critical portable applications, such as GPS receivers, connectivity, and sensing, power supply designers always had to choose between longer battery run time (from higher efficiency) or higher signal chain performance (from the increased sensor sensitivity possible with a quieter power supply). For line-powered industrial or communications equipment applications, designers have been forced to dissipate significant amounts of power in LDOs to achieve the desired noise performance. Achieving both low noise and high efficiency was impossible.
