The MAX1658/MAX1659 linear regulators maximize bat-
tery life by combining ultra-low supply currents and low
dropout voltages. They feature Dual Mode™ operation,
which presets the output to 3.3V (MAX1658) or 5V
(MAX1659), or permits it to be adjusted between 1.25V
and 16V. The regulator supplies up to 350mA, with a
typical dropout of 650mV for the MAX1658 and 490mV
for the MAX1659. With their P-channel MOSFET pass
transistor, these devices maintain a low quiescent cur-
rent from zero output current to the full 350mA, even in
dropout. They support input voltages ranging from 2.7V
to 16.5V.
The MAX1658/MAX1659 feature a 1µA shutdown mode,
reverse battery protection, short-circuit protection, and
thermal shutdown. They are available in a special high-
power (1.2W), 8-pin SO package designed specifically
for compact applications.

P-Channel Pass Transistor The MAX1658/MAX1659 feature an internal P-channel MOSFET pass transistor. Using a MOSFET provides several advantages over similar PNP designs, including lower dropout voltage and extended battery life.
