Notes to the characteristics
1. All characteristics are measured using the circuit shown in Fig.4
2. The circuit is DC adjusted at V
3. At 18 V < V
4. Conditions: V
5. Frequency response externally fixed.
6. Ripple rejection measured at the output with a source-impedance of 0
7. Ripple rejection measured at the output with a source-impedance of 0
8. Ripple rejection measured at the output with a source-impedance of 0
9. Noise voltage measured in a bandwidth of 20 Hz to 20 kHz.
10. Noise output voltage independent of R
