A6305

AiT Semiconductor Inc. www.ait-ic.com A6305 LOW DROPOUT VOLTAGE REGULATOR 300mA DUAL OUTPUT CMOS HIGH PSRR DESCRIPTION FEATURES The A6305 is a dual, low-noise, low-dropout regulator delivering at least 300mA of continuous output current. The output voltage for each regulator is set independently by trimming. Voltages are selectable in 100mV steps within a range of 1.5V to 4.5V. Typical output noise is 47μVRMS, and PSRR is 73dB at 100Hz. The A6305 includes two independent logic-controlled shutdown inputs and allows the output of each regulator to be turned of independently. The A6305 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module.              Two Low Dropout Voltage Regulators 300mA Output Current for Each LDO 20uA Operating Supply Current Per LDO Low 47μVRMS Output Noise Standby Mode:0.1μA Low 160mV Dropout at 300mA load 73dB PSRR at 100Hz Excellent Line regulation: 0.05%/V Independent Shutdown Controls 1.5V to 4.5V Factory-Preset Output Output Current Limit High Accuracy: ±2% (±1% customized) Available in SOT-26 and DFN6(2 x 2) Package The A6305 has excellent load and line transient response and good temperature characteristics, which can assure the stability of chip and power system.
