ADM7154 PSRR and Noise graphes

slmperl on Jul 6, 2020

Hello.

Why the PSRR and Noise graphed stop at 10MHz? Can I gae the data up to 200MHz?

Thanks

Shlomo

Hi slmperl,

The testing for LDO PSRR is only done up to 10MHz since the LDO only provides significant ripple rejection at this range of frequency.

Alex
