Performance Characteristics

4.3 Output Ripple Waveform

Figure 3 shows the output voltage ripple. This measurement was taken with the scope probe tip placed on

the J3 load terminal and the scope probe ground "barrel" pushed against the J4 load terminal. The scope

bandwidth is set to 20 MHz.

Bandwidth Limit = 20 MHZ
