Voltage Regulators 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 commu- nication possible. Furthermore, by decreasing the differ- ence between I/O voltages, drop in the power supply volt- age of VCO is reduced. 2.80 +0.20 –0.30 Unit: mm (0.65) 1.50 +0.25 –0.05 (0.65) 6 1 5 2 4 3 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 0.10 to 0.30 0.40±0.20 Applications • Cellular phones and others MINI-6D Block Diagram VOUT 4 1 VIN C2 2 Constant current Switch 6 On/Off 5 3 GND C1 1 AN8000MS Voltage Regulators Pin Descriptions Pin No. Symbol Description 1 VIN Input pin 2 C2 Capacitor connection pin 2 3 C1 Capacitor connection pin 1 4 VOUT Output pin 5 GND Ground pin 6 On/Off Control pin Absolute Maximum Ratings Parameter Symbol Rating Unit Supply voltage V IN 7.0 V Supply current I IN 20 mA Output current I O − 15 mA Allowable application voltage for V ON/OFF V IN V on/off pin Allowable maximum capacitance for C1 pin C 1 100 µ F Allowable maximum capacitance for C2 pin C 2 10 µ F Power dissipation * 2 P D 60 mW Operating ambient temperature * 1 T opr − 25 to + 75 ° C Storage temperature * 1 T stg − 40 to + 125 ° C Note) * 1: Except for the operating ambient temperature and storage temperature, all ratings are for T a = 25 ° C. * 2: The power dissipation shown is the value for T a = 75 ° C.
