Note 3. Output power is measured directly at the output pins of the IC.
Note 4. Frequency response externally fixed.
Note 5. Ripple rejection measured at the output with a source impedance of 0
(maximum ripple
amplitude of 2V)
Note 6. Frequency f = 100Hz.
Note 7. Frequency between 1kHz and 10kHz.
Note 8. Noise voltage measured in a bandwidth of 20Hz to 20kHz.
Note 9. Noise output voltage independent of R
