The MAX8559 dual, low-noise, low-dropout (LDO) linear regulator operates from a 2.5V to 6.5V input voltage and delivers at least 300mA of continuous output current. It offers low output noise and low dropout of only 60mV at 100mA. Typical output noise for this device is 32µV_RMS, and PSRR is 70dB at 10kHz. Designed with an internal p-channel MOSFET pass transistor, the MAX8559 maintains a low 115µA supply current per LDO, independent of the load current and dropout voltage. Other features include short-circuit protection and thermal-shutdown protection. The MAX8559 includes two independent logic-controlled shutdown inputs and is capable of operating without a bypass capacitor to further reduce total solution size. The MAX8559 is available in a miniature 8-bump UCSP™ (2mm x 1mm) or 8-pin TDFN (3mm x 3mm) package.
