Description

The AT97SC3204-X1A190 is an electronic component model belonging to the Application Specific Microcontrollers product category. It is a voltage regulator that can convert input voltages ranging from 1.8V to 5V to a user-settled output voltage. The regulator is capable of providing sourcing or sinking current and is often used in conjunction with series termination resistors. This makes it an ideal voltage source for active termination schemes in high-speed transmission lines, such as those found in high-speed memory buses and distributed backplane designs.
