Looking for 2A LDO with 80dB PSRR at 120Hz and 10kHz

Hi Jason,

We don't have an exact that device that can fit this requirement. Here are some options that can get fairly close. Also an article on how to optimize PSRR for LDOs which may help you meet your requirement.

LDO basics: power supply rejection ratio

One of the most touted benefits of low dropout linear regulators (LDOs) is their ability to attenuate voltage ripple generated by switched-mode power supplies. This is especially important for signal-conditioning…

Hi Jason,

LP5912 - specifically LP5912-3.3DRVR will have the best PSRR performance at 500mA.

If there is a specific range you are optimizing for, please refer back to PSRR tech article I linked before.
