1 / 7 page LR6156 Dual 300mA High PSRR LDO FEATURES • Two low dropout voltage regulators • 300mA output current for each LDO • 20uA operating supply current per LDO • Low 47uVRMS output noise • Standby Mode: 0.1uA • 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) APPLICATIONS • Cellular phones • Cordless phones and radio communication equipment • Battery Powered equipment • Notebook and hand-hold equipment • Wireless LAN • GPS receivers ORDERING INFORMATION DESCRIPTION The LR6156 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 47uVrms,and PSRR is 73dB at 100Hz. The LR6156 includes two independent logic-controlled shutdown inputs and allows the output of each regulator to be turned of independently. The LR6156 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module. The LR6156 has excellent load and line transient response and good temperature characteristics, which can assure the stability of chip and power system. And it uses trimming technique to guarantee output voltage accuracy within±2%. The LR6156 is available in SOT-23-6 package which is lead(Pb)- free LR6156 –X X XX TYPICAL APPLICATION APPLICATION HINTS NOTE: Input capacitor (Cin=1uF) and Output capacitor (Cout=1uF/3.3uF) arerecommended in all application circuit.
