Dual, 300mA, Low-Noise Linear Regulator  
with Independent Shutdown in UCSP or TDFN  
General Description  
Features  
♦ Two Low-Dropout-Voltage Regulators  
♦ Low 32µV Output Noise  
♦ 300mA Output Current for Each LDO  
♦ 70dB PSRR at 10kHz  
♦ Independent Shutdown Controls  
♦ Low 60mV Dropout at 100mA Load  
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 cur-  
rent. It offers low output noise and low dropout of only  
60mV at 100mA. Typical output noise for this device is  
RMS  
32µV  
, and PSRR is 70dB at 10kHz. Designed with  
RMS  
an internal P-channel MOSFET pass transistor, the  
MAX8559 maintains a low 115µA supply current per  
LDO, independent of the load current and dropout volt-  
age. 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 avail-  
able in a miniature 8-bump UCSP™ (2mm x 1mm) or  
8-pin TDFN (3mm x 3mm) package.  
♦ 115µA Operating Supply Current per LDO  
♦ 1.5V to 3.3V Factory-Preset Output  
♦ Small Ceramic Output Capacitors  
♦ Output Current Limit  
♦ Thermal-Overload and Short-Circuit Protection  
♦ 1.95W Power-Dissipation Capability (TDFN)  
♦ 2mm2 Footprint (UCSP)
