Note 3. Frequency response externally fixed.

Note 4. Ripple Rejection measured at the output with source impedence of 0Ω (maximum ripple

amplitude of 2V) and a frequency between 100Hz and 20kHz.

Note 5. Noise voltage measured in a bandwidth of 20Hz to 20kHz.

Note 6. Noise output voltage independent of RS (VI = 0V).

Note 7. Output power is measured directly at the output pins on the IC.
