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+15 µH for 8 Ω)

All measurements are made with CS1 = 1 µF and CS2 = 100 nF (Figure 3), except for the

PSRR where CS1 is removed (Figure 4).
