MAX8873T/S/R, MAX8874T/S/R
Low-Dropout, 120mA Linear Regulators
_______________General Description
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-
pendent of load, making these devices ideal for
battery-operated portable equipment such as cellular
phones and cordless phones.
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
protection, and reverse battery protection. 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
