This application solution details how a dual-channel LDO may be used to provide a dynamic voltage scaling output. This functionality is of particular interest when powering microcontrollers that have a wide operating voltage range: it is advantageous, when possible, to lower the operating voltage of the MCU in order to achieve lower power consumption.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
