Figure 4 - The circuit in figure 4 is the application of the IRU3034 which is done using a dual layout with IRU3033 in
a switching mode only. This circuit can be used to generate a low cost 5V to 3.3V for either Pentium application
with AGP socket or in Pentium II applications where it is desirable to generate an accurate on-board 3.3V supply.
