Notes to the characteristics
1. The circuit is DC adjusted at V
P
= 6 V to 17.5 V and AC operating at V
P
= 8.5 V to 17.5 V.
2. At 17.5 V < V
P
< 30 V the DC output voltage ≤ V
P
/2.
3. Output power is measured directly at the output pins of the IC.
4. Frequency response externally fixed.
5. Ripple rejection measured at the output with a source impedance of 0 Ω (maximum ripple amplitude of 2 V).
6. Frequency f = 100 Hz.
7. Frequency between 1 kHz and 10 kHz.
8. Frequency between 100 Hz and 10 kHz.
9. Noise voltage measured in a bandwidth of 20 Hz to 20 kHz.
10. Noise output voltage independent of R
S
(V
I
= 0 V).
