further information.
Product Description
CAMDs P/Active 27A02 Precision Voltage Divider Network is designed to work with the Linear Technology LTC1266
Synchronous Regulator Controller and LT1431 Programmable Reference commonly used in Pentium P54/P55C power
regulator designs. CAMDs P/Active technology provides precision ratio tracking over temperature/time required for proper
voltage regulation by the Pentium processor.
