_______________General Desc ription
The MAX8865 and MAX8866 dual, low-dropout linear
regulators operate from a +2.5V to +5.5V input range
and deliver up to 100mA. At 200mA total load, the
PMOS pass transistors keep the supply current at
145μA, making these devices ideal for battery-operated
portable equipment such as cellular phones, cordless
phones, and modems.
The devices feature Dual Mode operation: their out-
put voltages are 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 external resistor dividers. Other
features include independent low-power shutdown,
short-circuit protection, thermal shutdown protection,
and reverse battery protection. The MAX8866 also
includes an auto-discharge function, which actively dis-
charges the selected output voltage to ground when
the device is placed in shutdown mode. Both devices
come in a miniature 8-pin μMAX package.
