Triple Low Dropout Regulator Controllers POWER MANAGEMENT Description The SC1112 was designed for the latest high speed motherboards. It includes three low dropout regulator controllers. The controllers provide the power for the system AGTL bus Termination Voltage, Chipset, and clock circuitry. An adjustable controller with a 1.2V reference is available, while two selectable outputs are provided for the VTT (1.25 V or 1.5V, SC1112) or (1.2V or 1.5V, SC1112A) and the AGP (1.5V or 3.3V). The SC1112 low dropout regulators are designed to track the 3.3V power supply as the VTTIN supply is cycled On and Off. A latched short circuit protection is also available for the VTT output.
