ETA5057
80dB PSRR, Low Noise, RF, 350mA LDO in SOT353-5
DESCRIPTION
ETA5057 is a low-dropout (LDO) low-power linear voltage regulator features high power-supply rejection ratio (PSRR), ultralow-noise, fast startup, 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. Therefore, ETA5057 is an ideal power supply for noise-sensitive applications such as cellphones, CMOS sensors, RF transmissions and audios etc. ETA5057’s output voltage is adjustable through external feedback resistors and is housed in SOT353-5 package.
