UR5512

UNISONIC TECHNOLOGIES CO., LTD UR5512 LINEAR INTEGRATED CIRCUIT 2A DDR BUS TERMINATION REGULATOR  DESCRIPTION The UTC 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 UTC 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-I and 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  ORDERING INFORMATION Ordering Number Lead Free Halogen Free UR5512L-S08-R UR5512G-S08-R UR5512L-SH2-R UR5512G-SH2-R UR5512L-TN5-R UR5512G-TN5-R 1 Package SOP-8 HSOP-8 TO-252-5 SOP-8 HSOP-8 TO-252-5 Packing Tape Reel Tape Reel Tape Reel UR5512G-S08-R (1)Packing Type (2)Package Type (3)Green Package (1) R: Tape Reel (2) S08: SOP-8, SH2: HSOP-8, TN5: TO-252-5 (3) G: Halogen Free and Lead Free, L: Lead Free www.unisonic.co...
