Low-Dropout, 120mA Linear Regulators
3,MAX864TS/R
_______________General Description
____________________________Features
o Low Cost
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.
o Low, 55mV Dropout Voltage @ 50mA I
OUT
o Low, 68µA No-Load Supply Current
Low, 80µA Operating Supply Current (even in
dropout)
o Low, 350µV
Output Noise
RMS
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 package.
