13.2 RMS Noise
The RMS output voltage noise is listed in Table 3 for a range of load capacitances. Larger capacitances
result in smaller bandwidth and hence, smaller RMS noise.

13.3 Typical Noise Waveforms
An example of typical output voltage noise waveforms is plotted in Figure 9 for a range of load
capacitances. All cases share the same noise density but the reduced bandwidth with larger
capacitances results in smaller RMS noise, as listed in Table 3.
