The MAX8863T/S/R and MAX8864T/S/R low-dropout lin-

ear regulators operate from a +2.5V to +6.5V input

range and deliver up to 120mA. A PMOS pass transis-

tor allows the low, 80µA supply current to remain inde-

pendent 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 out-

put 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 fea-

tures include low-power shutdown, short-circuit protec-

tion, thermal shutdown protection, and reverse battery

protection. The MAX8864 also includes an auto-dis-

charge function, which actively discharges the output

voltage to ground when the device is placed in shut-

down mode. Both devices come in a miniature 5-pin

SOT23-5 package.
