Overview
UNISONIC TECHNOLOGIES CO.
, LTD UR5517 LINEAR INTEGRATED CIRCUIT 3A DDR BUS TERMINATION REGULATOR  DESCRIPTION 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 low level, VTT will be turned off and left Hi-Z(sleep-state mode).
If setting S5 were set in low level, both VTT and VTTREF will be turned off and discharged to ground(soft-off mode).
 FEATURES * Input Voltage Range:3~5.
5V *...
