AN8000MS
Ripple filter IC for cellular phones
s 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 commu-
nication possible. Furthermore, by decreasing the differ-
ence between I/O voltages, drop in the power supply volt-
age of VCO is reduced.
s Features
The I/O drop voltage is reduced to 0.3 V (A PNP tran-
sistor is used for the pass transistor)
The mounting area is reduced by adopting the mini-type
6-pin package
s Applications
Cellular phones and others
