PRELIMINAR

Y

P/ACTIVE PRECISION VOLTAGE DIVIDER NETWORK

FOR LINEAR TECHNOLOGY LTC1266/LT1431

Features

• Provides a complete Pentium regulator solution when

combined with a Linear Technology LTC1266/LT1431

Power Supply Regulator Circuit

• Miniature SOT and SOIC packages

• Thin film tightly ratio matched resistors using

P/Active technology

SCHEMATIC CONFIGURATION

Product Description

CAMD’s 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. CAMD’s P/Active technology provides precision ratio tracking over temperature/time required for proper

voltage regulation by the Pentium processor.
