An ideal op-amp would have infinite PSRR
Power supply rejection ratio (PSRR) determine how much noise from the input couples into the output. It is called as supply voltage rejection ratio (SVRR).
$({\rm{Power\;supply\;rejection\;ratio}} = \frac{{{{\rm{V}}_{{\rm{ripple}}\left( {{\rm{in}}} \right)}}}}{{{{\rm{V}}_{{\rm{ripple}}\left( {{\rm{out}}} \right)}}}})$
This term is expressed in microvolts per volt or decibels.
