[1] Output power is measured directly at the output pins of the IC.
[2] Frequency response externally fixed.
[3] Ripple rejection measured at the output with a source impedance of 0 Ω, maximum ripple amplitude of
2 V (p-p) and a frequency between 100 Hz and 10 kHz.
[4] Noise voltage measured in a bandwidth of 20 Hz to 20 kHz.
[5] Noise output voltage independent of R_S (V_I = 0 V).
