Dual, Low-Dropout, 100mA Linear Regulators

_______________General Description

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.
