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