1 / 7 page UNISONIC TECHNOLOGIES CO., LTD UR5512 LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 7 Copyright © 2005 Unisonic Technologies Co., Ltd QW-R101-017,A 2A DDR BUS TERMINATION REGULATOR DESCRIPTION The UR5512 is a linear regulator which provides up to 2 Amp bi-directional driving and sinking capability for DDR SDRAM bus terminator application. The output termination voltage tracks the reference voltage applied at VREF pin. A resistor divider connected to VIN, GND and VREF pins is used to force a reference voltage to VREF pin. The UR5512 contains a high-speed operational amplifier to provide excellent response to line/load transient. An active-low shutdown (VREF) pin provides Suspend to RAM (STR) functionality. Additional features include current limiting protection, on-chip thermal shut-down protection. FEATURES * DDR-II Termination Voltage applications * Driving and sinking current up to 2A * Low output voltage offset (within 20mV@±2A) * Adjustable output voltage by external resistors * Suspend to RAM (STR) functionality * Current limiting protection * Thermal protection * Cost-effective and easy to use HSOP-8 *Pb-free plating product number: UR5512L ORDERING INFORMATION Order Number Normal Lead Free Plating Package Packing UR5512-SH2-R UR5512L-SH2-R HSOP-8 Tape Reel UR5512-SH2-T UR5512L-SH2-T HSOP-8 Tube UR5512L-SH2-R (1)Packing Type (2)Package Type (3)Lead Plating (1) R: Tape Reel, T: Tube (2) SH2: HSOP-8 (3) L: Lead Free Plating, Blank: Pb/Sn |
