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
