1 High PSRR Low Noise 300mA Dual LDO Regulators High PSRR Low Noise 300mA Dual LDO Regulators INTRODUCTION The are a group of dual channel low-dropout voltage regulators designed for portable and wireless applications thatt require high PSRR, low quiescent current and excellent line and load transient response. The CE6211 includes a reference voltage source, error amplifiers, driverr transistors, current limiters and phase compensators internally. The CE6211 is stable with a small 1μF ceramic on the output, which is ideal for battery powered systems for delivering low dropout voltage and low quiescent current. It provides up to 300mA at each channel, from a 2.0V to 6.0V input. The CE6211 is available in 6 pin SOT-23 package. FEATURES Shutdown Current: < 0.1µA Current: 300mA Range: 1.2V ~ 5.0V, (selectable in 0.1V steps) High Accuracy: ±2% (Typ.) Dropout : 100mV@100mA(3.0V Typ.)
