Description
The MAX1589 low-dropout linear regulator operates
from a +1.62V to +3.6V supply and delivers a guaranteed
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 reaches
regulation. This device is offered in 6-pin thin SOT23
and 6-pin 3mm x 3mm thin DFN packages.
An internal PMOS pass transistor maintains low supply
current, independent of load and dropout voltage, making
the MAX1589 ideal for portable battery-powered equipment
such as personal digital assistants (PDAs), digital
still cameras, cell phones, cordless phones, and notebook
computers. Other features include logic-controlled
shutdown, short-circuit protection, and thermal-overload
protection.
