Hello team,
TPS7B82-Q1 D/S shows the PSRR up to 50MHz @ Iout=10mA / 100mA.
Do you have the data of the PSRR up to 200MH @ Iout =10mA / 100mA?
Thanks.
Regards,
Hirata

Hi Hirata-san,
No we do not have equipment to measure PSRR at such high frequencies. One of the reasons for that is that LDO's generally have a bandwidth which is less than 5MHz and so the LDO does not actively provide PSRR at higher frequencies.
Any attenuation of the input signal (PSRR) at these very high frequencies will be dominated by the capacitors used and the PCB parasitics.
Hi Kyle-san,
Thanks so much for your detailed answer.
I will let you know if i need further support.
I appreciate your support.
