The MAX8873T/S/R and MAX8874T/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, 82µA supply current to remain inde-

p e nd e nt of loa d , ma king the s e d e vic e s id e a l for

battery-operated portable equipment such as cellular

phones and cordless phones.

♦ LP2980 Pin-Compatible SOT23 Package

♦ Low, 55mV Dropout Voltage at 50mA I

(130mV at 120mA)

OUT

♦ Low, 73µA No-Load Supply Current

Low, 82µA Operating Supply Current (even in

dropout)

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. Total error on

the output is ±3.5%. Output voltages are set on the low

side of popular ranges so that power drain is minimized

for longer battery life. Other features include low-power

shutdown, short-circuit protection, thermal shutdown

p rote c tion, a nd re ve rs e b a tte ry p rote c tion. The

MAX8874 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.

♦ Miniature External Components

♦ Thermal Overload Protection

♦ Output Current Limit

♦ Reverse Battery Protection

♦ Dual Mode Operation: Fixed or Adjustable

(1.25V to 6.5V) Output

♦ Low-Power Shutdown
