Power Sub-system
2.1.5.5 Voltage Regulation
The power supply output voltages are within the following voltage limits when operating at
steady state and dynamic loading conditions. These limits include the peak-peak ripple/noise.
All outputs are measured with reference to the return remote sense signal (ReturnS). The 5V,
12V1, 12V2, –12V and 5VSB outputs are measured at the power supply connectors referenced
to ReturnS. The +3.3V is measured at the remote sense signal (3.3VS) located at the signal
connector.
