Electrical characteristics curves

The graphs shown in this section use the following abbreviations:

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

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

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

PSRR where CS1 is removed (see Figure 3).
