Figure 19: Input Reflected Ripple Current, is, through a 10 H source
inductor at nominal input voltage and rated load current (5 mA/div).
3.3V and 5.0V outputs at full rated load current. (see Fig. 17)
Figure 20: Output Voltage Ripple at nominal input voltage and rated
load current on both outputs (50 mV/div). Load capacitance: 1F
ceramic & 15F tantalum. Bandwidth: 20 MHz. (see Fig. 17)
