SC1112STR Description

Short technical summary and product information.

The Semtech SC1112STR is a triple low dropout regulator controller designed for high-speed motherboards, specifically for applications like Intel Pentium III motherboards. It offers three independent regulator controllers to power system AGTL bus termination voltage, chipset, and clock circuitry.

 

This controller features selectable and adjustable output voltages. One controller is adjustable with a 1.2V reference. The other two provide selectable outputs for VTT (1.25V or 1.5V) and AGP (1.5V or 3.3V). The SC1112 is designed to track the 3.3V power supply as the VTTIN supply cycles on and off. It includes an integrated charge pump for adequate gate drives for external MOSFETs and a programmable delay for the power good signal. A latched short circuit protection is available for the VTT output.

 

The SC1112STR is supplied in a 16-SOIC (0.154", 3.90mm Width) surface mount package. It operates within a temperature range of 0°C to 70°C (TA).
