| Voltage Regulators 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 communication possible. Furthermore, by decreasing the difference between I/O voltages, drop in the power supply voltage of VCO is reduced.
