the effect of adding a 500-milliampere load. In both cases, the output voltage was
adjusted to minimum (+6 volts). Figure 6.11(c) shows the results of maximum
input voltage under no-load conditions; finally, Figure 6.11(d) illustrates the cir-
cuit performance under conditions of maximum input voltage and a 500-
milliampere load. The measured performance of the circuit is summarized and
contrasted with the original design goals in Table 6.2.
