    Hi Andres,

    Do you have similar device with higher PSRR? as TLV755 only 52dB@1khz, ME6211 has 70dB@1khz, customer care about PSRR as LDO is used in audio speaker, customer require >60dB@1khz

    Hi Amber,

    The other LDO which could meet the PSRR requirement, however in a different package, would be LP5912 which offers 75dB @ 1kHz.
