Low-Input-Voltage, 500mA LDO Regulator
with R E S E T in SOT and TDFN
General Description
Features
The MAX1589 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.
An internal PMOS pass transistor maintains low supply
current, independent of load and dropout voltage, making
the MAX1589 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-
