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 0Ω (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 RS (VI = 0V).
