3.1 Test Data and Performance Curves

Figure 3-1 through Figure 3-7 present typical performance curves for the LM25148B-Q1EVM-2100. Because actual performance data can be affected by measurement techniques and environmental variables, these curves are presented for reference and can differ from actual field measurements.
