power-supply rejection ratio

[¦pau̇·ər sə‚plī ri′jek·shən ‚rā·shō]
(electronics)
The ratio between the gain of an amplifier for difference signals between the input terminals, and the gain for variations of the power-supply voltages. Abbreviated PSRR.

The integrated LDOs feature high 65-dB PSRR (power-supply rejection ratio) performance that ranges from 1 kHz to 10 kHz, lowering output noise to 80 ?V/rms for powering sensitive analog circuitry.
These devices also feature low quiescent current of 135 [micro]A (typ.), offset voltage of 3.5 mV (max.), common mode rejection ratio (CMRR) of 100 dB (typ.), and power-supply rejection ratio (PSRR) of 102 dB (typ.).
