  • Description

    The APM5331 is an electronic component model in the IC Chips product category. It is a regulator designed to convert voltage supplies ranging from 1.6V to 6V into a desired output voltage. The regulator can source or sink up to 3A of peak current while regulating the output voltage to within 2% (DDR 1) and 3% (DDR 2) or less. It is commonly used in high-speed memory buses, distributed backplane designs, and as a termination voltage for DDR SDRAM.
