The RP122 is a very low noise, high speed response LDO for applications requiring a stable voltage supply under all conditions. The ripple rejection at 100kHz is between 6dB and 13dB higher than similar competitor parts, resulting in excellent RFI emmunity.
The LDO is ideally suited to high performance ADCs and DACs, and mixed signal ICs.
A full range of values are available from 1.2V to 4.8V in 0.1V steps.
