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.
