3.4 Load Transients

Load transient response is shown in the following figures. The slew rate is set to 0.16 A/μs. The figure shows the load transient of OUTPUT1 with the other outputs at full load and the input voltage at 12 V. The load current is sourced from the 18 V directly to the –2.5 V with no COM connection.
