Notes to the characteristics
1.
All characteristics are measured using the circuit shown in Fig. 4.
2.
The circuit is DC adjusted at Vp= 6V to 18V and AC operating at Vp= 8,5V to 18 V.
3.
At 18 V < Vp< 30 V the DC output voltage < Vp/2.
4.
Output power is measured directly at the output pins of the IC.
5.
Frequency response externally fixed.
6.
Ripple rejection measured at the output with a source impedance of 0 ^
(maximum ripple amplitude of 2 V) and a frequency between 100 Hz and 10 kHz.
7.
Noise voltage measured in a bandwidth of 20 Hz to 20 kHz.
8.
Noise output voltage independent of Rn (V j = 0 V).
