A.4.4 Circuit Performance
Figure 18 shows the characteristics of the implemented circuit. The lower trace is the system’s
+5 V supply, current limited at 500 mA. The upper trace is the Module’s 3.3 V supply. The
voltage sag on the +5 V system supply (lower trace) is limited to 0.24 V, keeping it within
+5.0 ±5% range for proper system operation.
