钰泰 ETA5053 低压差低功率线性电压调节器

　　DESCRIPTION

　　ETA5053 is a fixed output, 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 70dB with quiescent current is about 35uA.

　　Therefore,ETA5053 is an ideal power supply for noise-sensitiveapplications such as 1 RF transmissions, cellphones,CMOS sensors and audios etc.

　　ETA5053 is available in DFN1x1and SOT23-5.
