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

* VLDOIN Voltage Range:1.2V~3.6V

* DDR1/2/3 Termination Voltage Applications

* Sourcing and Sinking Current up to 3A

* ±20mV Accuracy for VTT and VTTREF

* 10mA Buffered Reference(VTTREF)

* Supports High-Z in S3(STR) and Soft-off in S5(Shutdown)

* Integrated Divider Tracks 1/2 VDDQSNS for Both VTT&VTTREF

* Built-In Soft-Start

* Current Limiting Protection

* Thermal Shutdown Protection
