Test Setup and Results
2.3
Output Voltage Regulation
The load regulation for the EVM is shown in
. The line regulation for the EVM is shown in
. Measurements are given for an ambient temperature of 25°C.

Load Transients and Loop Response
The EVM response to load transients is shown in
. 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.
