3.1
Electrical characteristics 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 F + 30 H for 4
Ω and 0. 5F + 60 H for 8 Ω)
All measurements are done with CS1 = 1 F and CS2 = 100 nF (see Figure 2), except for the
PSRR where CS1 is removed (see Figure 3).
