150mA DUAL OUTPUT CMOS LOW NOISE
LOW-DROPOUT VOLTAGE REGULATOR
LR6155
Description
The LR6155 is a dual output, low noise, low-dropout regulator delivers at least 150mA 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 1.3V to 5.0V. Typical output noise is 27uVRMS, and PSRR is 65dB at 1KHz.
The LR6155 includes two independent logic-controlled shutdown inputs and allows the output of each regulator to be turned of independently. The LR6155 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module.
