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.).
