General Description
The MAX8885 low-dropout (LDO) linear regulator operates
from a +2.5V to +6.5V input voltage range and delivers up
to 150mA. It uses a P-channel MOSFET pass transistor to
allow a low 85μA supply current—which is independent of
the load—as well as LDO voltage. The MAX8885 is opti-
mized to operate with low-cost, high-ESR output capaci-
tors such as small case-size tantalum capacitors. It is ideal
for cost-sensitive portable equipment such as PCS and
cellular phones. For a pin-compatible, functionally equiva-
lent device for use with a low-ESR, ceramic output capaci-
tor, refer to the MAX8875 data sheet.
The MAX8885 features a power-OK output that indicates
when the output is out of regulation, and is available in
preset output voltage versions of 5.0V, 3.3V, 3.0V, 2.7V,
and 2.5V. Other features include 1μA (max) shutdown cur-
rent, short-circuit protection, thermal shutdown protection,
and reverse-battery protection. The MAX8885 is available
in a miniature 5-pin SOT23 package.
