| XC6406 Series High Current Dual Positive Regulator ETR0310_001 GENERAL DESCRIPTION The XC6406 series are highly precise, low power consumption, dual positive regulators. They are fabricated using Torex's CMOS process. Performance features of the series include high current and low dropout voltage, and the series features a voltage reference, and error amplifier, a current limiter and a phase compensation circuit plus a driver transistor. Output voltage of each regulator 1 and regulator 2 is selectable in 100mV increments within the range of 1.8V to 6.0V. The XC6406 series is available in the SOP-8 package. APPLICATIONS CD-ROM, DVD Battery powered equipment PDAs Cameras, Video recorders Portable AV equipment Reference voltage FEATURES Maximum Output Current Maximum Operating Voltage Accuracy Low Power Consumption Line Regulation Output Voltage Temperature Range Dropout Voltage Small Packages : 100 ppm/ (TYP.) : 150mV@100mA : 300mV@200mA : SOP-8 : SOP-8FD (Under development) Operating Temperature Range : - 40 ~ 85 : 400mA (within the power dissipation) : 8.0V :2% : 20A (TYP.) : 0.2% / V (TYP.)
