Selecting the Best Multi-Sourced Linear Regulator Slide 8

While datasheet electrical characteristics table may imply parity between two linear regulators, the rejection ratio may vary considerably over the frequency of the input ripple. For example, TI’s LM1117-N may show poorly at lower frequencies but is better at frequencies typical of 60 Hz power supplies and audio applications.
