TYPICAL APPLICATION
Pentium with AGP
Figure 3- Typical application of US3004 in a Pentium with AGP where the power dissipation of the 3.3V
linear regulator is equally distributed between Q3 and Q4 pass transistors. This equal distribution is
possible by accurately regulating the first regulator using the US3004 linear controller and its internal 1%
reference voltage while the second controller regulates the output of the first regulator from 4.17V to
3.3V, thereby distributing the power dissipation equally.
