2.3 Output Voltage Regulation
The load regulation for the EVM is shown in Figure 3. The line regulation for the EVM is shown in
Figure 4. Measurements are given for an ambient temperature of 25°C.

2.4 Load Transients and Loop Response
The EVM response to load transients is shown in Figure 5. The current step is from 25% to 75% of
maximum rated load at 9 V input. The current step-slew rate is 100 mA/µs. Total peak-to-peak voltage
variation is as shown, including ripple and noise on the output.
The EVM loop-response characteristics are shown in Figure 6. Gain and phase plots are shown for V
