ETA5030
70dB PSRR, Low Noise, Fast Response 300mA LDO in SOT23-3
ETA5030 is a fixed output, low-dropout (LDO) low-power linear voltage regulator which 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 70dB at 1KHz with quiescent current of about 35uA.
