WebPower supply rejection is actually a unusual term applied to voltage regulators. This term makes more sense for a part with some analog output, like a opamp. However, a voltage … WebPSRR (Power Supply Rejection Ratio) is a measure of how well a circuit rejects noise of various frequencies from a particular device's power supply. More specifically, from a device's voltage input. Optimally, if the voltage input of a device changes, the output should not change. Unfortunately, this is almost always not the case.
