This five-part series provides an overview of DC-DC converters.
This five-part series provides an overview of linear regulators.
These training videos will be used to better understand LDOs, and includes more information on designing the best ADC power supply, stabilizing an LDO, measuring LDO noise and power supply rejection ratio, sourcing 5-A or more with current sharing regulators, measuring thermal resistance between junction temperature and ambiance, and measuring the ADC power supply rejection.
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.
