rejection
[1] A minimum load of 3 Ω is allowed at supply voltages > 22 V.
[2] Supply voltage ripple rejection is measured at the output, with a source impedance ZS = 0 Ω at the input
and with a frequency range from 20 Hz to 22 kHz (unweighted). The ripple voltage is a sine wave with a
frequency fripple and an amplitude of 300 mV (RMS), which is applied to the positive supply rail.
