5.1 OUTPUT VOLTAGE RIPPLE

Ripple and noise shall be measured using the following methods:

Outputs bypassed at the point of measurement with a parallel combination of 10µF tantalum capacitor in parallel with 0.1µF

ceramic capacitors, referring the setup in

Figure 19.

The ripple voltage is measured with 20 MHz BWL.
