Description
ACE520 dual, low-noise, low-dropout regulator delivers at least 300mA of continuous output current. The output voltage for each regulator is set independently by trimming. Output voltages are selectable in 100mV steps within a range of 1.2V to 3.5V. Typical output noise is 47uVrms,and PSRR is 73dB at 100Hz. The ACE520 includes two independent logic-controlled shutdown inputs and allows the output of each regulator to be turned of independently.
