产品概述 返回TOP
CXLD64339 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 with a 0.1μF bypass capacitor. Therefore, CXLD64339 is anideal power supply for noise-sensitive applications such as RF transmissions, cellphones, CMOS sensors and audios etc. CXLD64339’s output voltage is factory set and is housed in SOT23-5 package.
