CNS1105 is a low-dropout (LDO) linear voltage regulator that features ultra-high power supply rejection ratio (PSRR), ultra-low quiescent current,fast start-up, and excellent line and load transient responses. Its PSRR can be as high as 102dB at
1.2V output. Therefore, CNS1105 is an ideal power supply for noise-sensitive applications such as RF transmissions, cellphones, CMOS sensors and audios etc.
