CM3106
2 Amp Source/ Sink Bus
Termination Regulator
Product Description
The CM3106 is a sinking and sourcing regulator specifically
designed for providing power to DDR memory terminating resistors
and companion chip set V_TT power. The output voltage accurately
tracks V_DDQ/2. The CM3106 can source and sink current up to 2 A,
ideal for DDR−I memory systems, and 1.2 A for DDR−II systems,
while maintaining a load regulation of 0.5% in either application.
The CM3106 provides over current and over temperature protection
which protects the device from excessive heating due to high current
and high temperature. A shutdown capability using an external
transistor reduces power consumption and provides a high impedance
output.
The CM3106 is housed in an 8−lead SOIC RoHS−compliant
package.
