Hi, I had read that power supply rejection ratio(PSRR or PSR) follows open-loop gain curve(or CMRR curve) meaning it drops off with frequency. I saw that in many opam datasheets like OP1177 etc but when looking at LM386 data sheet(page 4, PSR Vs frequency curve) it shows reverse trend , meaning PSR increases with frequency . Can anyone comment about this revers behavior? Thanks
