Electrical characteristic curves
The graphs included in this section use the following abbreviations:
RL + 15μH or 30μH = pure resistor + very low series resistance inductor
Filter = LC output filter (1F+30H for 4
Ω and 0.5F+60H for 8Ω)
All measurements done with Cs1=1F and Cs2=100nF except for PSRR where Cs1 is
removed.
