MAX8863T/S/R,
MAX8864T/S/R Low-Dropout, 120mA Linear Regulators General Description The MAX8863T/S/R and MAX8864T/S/R low-dropout linear
regulators operate from a +2.5V to +6.5V input range and
deliver up to 120mA. A PMOS pass transistor allows the
low, 80μA supply current to remain independent of load,
making these devices ideal for battery-operated portable
equipment such as cellular phones, cordless phones, and
modems.
The devices feature Dual Mode™ operation: their output
voltage is preset (at 3.15V for the T versions, 2.84V for
the S versions, or 2.80V for the R versions) or can be
adjusted with an external resistor divider. Other features
include low-power shutdown, short-circuit protection, thermal
shutdown protection, and reverse battery protection. The
MAX8864 also includes an auto-discharge function, which
actively discharges the output voltage to ground when the
device is placed in shutdown mode. Both devices come in
a miniature 5-pin SOT23 package. Applications
