AN8000MS

Ripple filter IC for cellular phones

■ Overview

The AN8000MS is a ripple filter IC that rejects the ripple component superimposed on the regulator output. Use for the VCO bias of cellular phones improves C/N and S/N and makes the high-quality telephone communication possible. Furthermore, by decreasing the difference between I/O voltages, drop in the power supply voltage of VCO is reduced.

■ Features

•The I/O drop voltage is reduced to 0.3 V (A PNP transistor is used for the pass transistor)

•The mounting area is reduced by adopting the mini-type 6-pin package

■ Applications

• Cellular phones and others
