4.4 Output Voltage Line Regulation
Figure 3 shows the line regulation for the EVM with a 2.4-Ω (2.1 A) load.

4.5 Load Transients
Figure 4 shows the EVM's response to load transients. The current step is from 25% to 75% of maximum
rated load at a 3.6-V input respectively. 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.
