RE: Opamp implemented for power supply circuit.

Linear regulator manufacturers often plot expected ripple rejection with respect to frequency, often up to 100kHz or more, for these "DC" circuits.

Linear regulator manufacturers often speak of the spectral content of noise on the output. One can deduce that noise currents typical to bipolar input op amps will develop noise voltages across the 10k resistors on the inputs of this op amp which start to exceed quoted output noise ratings for common voltage regulators. High quality fet input op amps can be quite a bit better in this regard.
