UR5517 3A DDR BUS TERMINATION REGULATOR

The UR5517 is a linear regulator which provides up to 3 Amp bi-directional sourcing and sinking capability for DDR1/2/3 SDRAM bus terminator applications. It only requires 20uF of ceramic output capacitance by a integrated operational amplifier which provides fast load transient response. The UR5517 also includes two control pins, S3 & S5. If S3 were set in .
