PSRR of low dropout voltage regulators
https://www.electronics-lab.com/psrr-low-dropout-voltage-regulators/
Here’s an app note about PSRR of LDO from Microchip. The Power Supply Rejection Ratio is the ability of a device, such as a Low Dropout Voltage regulator, to reject the various perturbations that can be found in its input supply rail by providing a greatly attenuated signal at the output. Generally, the main source […]
