Electrical characteristic curves

The graphs shown in this section use the following abbreviations:

● RL+ 15 µH or 30 µH = pure resistor + very low series resistance inductor

● Filter = LC output filter (1 µF+30 µH for 4 Ω and 0.5 µF+60 µH for 8 Ω)

All measurements are done with CS1=1 µF and CS2=100 nF (see Figure 2, except for the

PSRR where CS1 is removed (see Figure 3).
