10.3.2.9 DC/DC Converters Voltage Regulation
The DC/DC converters’ output voltages stay within the following voltage limits when operating
at steady state and dynamic loading conditions. These limits include the peak-peak
ripple/noise specified in Table 82. The 3.3V and 5V outputs are measured at the remote sense
point, all other voltages measured at the output harness connectors.

10.3.2.10 DC/DC Converters Dynamic Loading
The output voltages remains within limits specified in table above for the step loading and
capacitive loading specified in the table below. The load transient repetition rate is only a test
specification. The ∆ step load may occur anywhere within the minimum load to the maximum
load shown in Table 77 and Table 78.
