ETA5057
80dB PSRR, Low Noise, RF, 350mA LDO in SOT353-5
ETA5057 is a low-dropout (LDO) low-power linear voltage regulator features high power-supply rejection ratio (PSRR), ultralow-noise, fast start-up, and excellent line and load transient responses. Its PSRR can be as high as 80dB and its noise level can be as low as 30μVRMS of output voltage noise at 2.8V output.
