钰泰半导体 ETA5052 低功耗线性稳压器芯片

　　DESCRIPTION

　　ETA5052 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. lts 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 with a 0.1μF bypass capacitor. Therefore, ETA5052 is an ideal power supply for noise-sensitive applications such as RF transmissions,cellphones,CMOS sensors and audios etc.

　　ETA5052's output voltage is adjustable through external feedback resistors and is housed in SOT23-6 package.
