Low-Input-Voltage, 500mA LDO Regulator  
RESET  
with  
in SOT and TDFN  
General Description  
Features  
o Low 1.62V Minimum Input Voltage  
o Guaranteed 500mA Output Current  
The MAX1589A low-dropout linear regulator operates  
from a +1.62V to +3.6V supply and delivers a guaran-  
teed 500mA continuous load current with a low 175mV  
dropout. The high-accuracy ( 0.5%) output voltage is  
preset to internally trimmed voltages from +0.75V to  
+3.0V. An active-low, open-drain reset output remains  
asserted for at least 70ms after the output voltage reach-  
es regulation. This device is offered in 6-pin thin SOT23  
and 6-pin, 3mm x 3mm thin DFN packages.  
o
0.5ꢀ Initial Accuracy  
o Low 175mV Dropout at 500mA Load  
o 70ms RESET Output Flag  
o Supply Current Independent of Load and Dropout  
Voltage  
o Logic-Controlled Shutdown  
o Thermal-Overload and Short-Circuit Protection  
o Preset Output Voltages (0.75V, 1.0V, 1.3V, 1.5V,  
An internal pMOS pass transistor maintains low supply  
current, independent of load and dropout voltage, making  
the MAX1589A ideal for portable battery-powered equip-  
ment such as personal digital assistants (PDAs), digital  
still cameras, cell phones, cordless phones, and note-  
book computers. Other features include logic-controlled  
shutdown, short-circuit protection, and thermal-overload  
protection.
