Product Description
The CM3106 is a sinking and sourcing regulator specif-
ically 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 2A,
ideal for DDR-I memory systems, and 1.2A for DDR-II
systems, while maintaining a load regulation of 0.5% in
either application.
The CM3106 provides over current and over tempera-
ture protection which protects the device from exces-
sive 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 both 8-lead SOIC and PSOP
packages and is available with optional lead-free finish-
ing.
