CM8561

CM8561 1.5A SINK & SOURCE ADJUSTABLE LINEAR BUS TERMINATOR GENERAL DESCRIPTION The CM8561 is a low cost linear regulator designed to provide a desired output voltage or termination voltage for various applications by converting voltage supplies ranging from 1.6V to 6.0V. The desired output voltage could be programmable by two external voltage divider resistors. The CM8561 is capable of sourcing or sinking up to 1.5A of current while regulating an output VOUT voltage to within 2% (DDR-I), 3% (DDR-II) or less. The CM8561 provides low profile 8-pin SOIC package to save system space. FEATURES Ideal for DDR-I and DDR-II 8-pin SOIC package Source and sink up to 1.5A, no heat sink required Integrated power MOSFETs Programmable output voltage by external resistors Output voltage could go down to 0.6V Iccq at VCCA ~ 230uA Current limit protection and Short Circuit protection Thermal shutdown protection Shutdown for standby or suspend mode operation Minimum external components APPLICATIONS Mother Board PCI/AGP Graphics Game/ Play Station Set Top Box IPC www.DataSheet4U.com SCSI-III Bus terminator PIN CONFIGURATION SOP-8 (S08) Top View 1 2 3 4 VIN VOUT REFEN VCCA GND GND GND GND 8 7 6 5 2006/10/11 Rev. 1.2 Champion Microelectronic Corporation Page 1 CM8561 1.5A SINK & SOURCE ADJUSTABLE LINEAR BUS TERMINATOR PIN DESCRIPTION Pin No. 1 2 5,6,7,8 3 4 VIN VOUT GND REFEN VCCA Symbol Input Power Output Voltage Ground Reference Voltage Input and Chip Enable Voltage supply for internal c...
