Notes

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).

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

5. Noise output voltage independent of Rs (VI = 0 V).
