General Description
The RT9174 is a triple linear regulator controller designed for motherboard application.
The regulators are intended to regulate the computer system AGP (2X/4X) power, the 2.5V clock power, and the 1.8V power for North/South Bridge core voltage and/or cache memory circuits. All controllers can drive NPN or NMOSFET pass transistor. A special scheme empoly driver voltage could be higher than VDD when driving NMOSFET through the 12V power.

FEATUREs
• Integrated Three Linear Controllers in a SOP-8 Package
