What is PSRR (power supply rejection ratio)?
A measure of how little supply-voltage variation reaches a circuit's output. The larger it is, the more immune the circuit is to supply noise.
PSRR (power supply rejection ratio) in the explanations
PSRR expresses how much supply-voltage variation appears at the output, in dB; higher means better immunity to supply noise.
