Notes
1. Output power is measured directly at the output pins of the device.
2. Frequency response externally fixed.
3. Ripple rejection measured at the output with a source impedance of 0 Ω; maximum ripple of 2 V (p-p) and at a
frequency between 100 Hz to 10 kHz.
4. Noise measured in a bandwidth of 20 Hz to 20 kHz.
5. Noise output voltage independant of Rs (Vi = 0 V).
