Notes to the characteristics
1. The circuit is DC adjusted at VP = 6 V to 18 V and AC operating at VP = 8.5 to 18 V.
2. At 18 V < VP < 30 V the DC output voltage ≤ VP/2.
3. Frequency response externally fixed.
4. Ripple rejection measured at the output with a source impedance of 0 Ω (maximum ripple amplitude of 2 V) and a
frequency between 100 Hz and 10 kHz.
5. Noise voltage measured in a bandwidth of 20 Hz to 20 kHz.
6. Noise output voltage independent of RS (VI = 0 V).
7. Output power is measured directly at the output pins of the IC.
