MAX8873T/S/R, MAX8874T/S/R
Low-Dropout, 120mA Linear Regulators
_______________General Description
____________________________Features
o LP2980 Pin-Compatible SOT23 Package
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.
o Low, 55mV Dropout Voltage at 50mA I
(130mV at 120mA)
OUT
o 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 3.5ꢀ. 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
devices come in a miniature 5-pin SOT23 package.

transistor. If the feedback voltage is lower than the refer-
ence, the pass-transistor gate is pulled lower, allowing more
current to pass and increasing the output voltage. If the
feedback voltage is too high, the pass-transistor gate is
pulled up, allowing less current to pass to the output.
The MAX8873/MAX8874 are low-dropout, low-quiescent-
current linear regulators designed primarily for battery-
powered applications. They supply an adjustable 1.25V to
6.5V output or a preselected 2.80V (MAX887_R), 2.84V
(MAX887_S), or 3.15V (MAX887_T) output for load currents
up to 120mA. These devices consist of a 1.25V reference,
error amplifier, MOSFET driver, P-channel pass transistor,
dual-mode comparator, and internal feedback voltage
divider (Figure 1).
The output voltage is fed back through either an internal
resistor voltage divider connected to the OUT pin, or an
external resistor network connected to the SET pin. The
dual-mode comparator examines the SET voltage and
selects the feedback path. If SET is below 60mV, internal
feedback is used and the output voltage is regulated to the
preset output voltage. Additional blocks include a current
limiter, reverse battery protection, thermal sensor, and shut-
down logic.
The 1.25V bandgap reference is connected to the error
amplifier’s inverting input. The error amplifier compares this
reference with the selected feedback voltage and amplifies
the difference. The MOSFET driver reads the error signal

Shutdown
A low input on the SHDN pin shuts down the
MAX8873/MAX8874. In shutdown mode, the pass tran-
sistor, control circuit, reference, and all biases are
turned off, reducing the supply current to typically
0.1nA. Connect SHDN to IN for normal operation. The
MAX8874 output voltage is actively discharged to
ground when the part is placed in shutdown (see
Typical Operating Characteristics).
Figure 2. Adjustable Output Using External Feedback
Resistors
Internal P-Channel Pass Transistor
The MAX8873/MAX8874 feature a 1.1Ω typical P-chan-
nel MOSFET pass transistor. This provides several
advantages over similar designs using PNP pass tran-
sistors, including longer battery life.
Current Limit
The MAX8873/MAX8874 include a current limiter that
monitors and controls the pass transistor’s gate volt-
age, estimating the output current and limiting it to
about 280mA. For design purposes, the current limit
should be considered 120mA to 420mA. The output
can be shorted to ground for an indefinite time period
without damaging the part.
The P-channel MOSFET requires no base drive current,
which reduces quiescent current considerably. PNP-
based regulators waste considerable amounts of cur-
rent in dropout when the pass transistor saturates. They
also use high base-drive currents under large loads.
The MAX8873/MAX8874 do not suffer from these prob-
lems, and consume only 82µA of quiescent current,
whether in dropout, light load, or heavy load applica-
tions (see Typical Operating Characteristics).
Thermal Overload Protection
Thermal overload protection limits total power dissipa-
tion in the MAX8873/MAX8874. When the junction tem-

perature exceeds T = +170°C, the thermal sensor
J
sends a signal to the shutdown logic, turning off the
pass transistor and allowing the IC to cool. The thermal
sensor turns the pass transistor on again after the IC’s
junction temperature typically cools by 20°C, resulting
in a pulsed output during continuous thermal overload
conditions.
In preset voltage mode, internal, trimmed feedback
resistors set the MAX887_R output to 2.80V, the
MAX887_S output to 2.84V, and the MAX887_T output to
3.15V. Select this mode by connecting SET to ground.
Thermal overload protection is designed to protect the
MAX8873/MAX8874 in the event of fault conditions.
Stressing the device with high load currents and high
input-output differential voltages (which result in die tem-
peratures above +125°C) may cause a momentary over-
shoot (2% to 8% for 200ms) when the load is completely
removed. This can be remedied by raising the minimum
load current from 0µA (+125°C) to 100µA (+150°C). For
continuous operation, do not exceed the absolute maxi-
In adjustable mode, select an output between 1.25V

Maximum power dissipation of the MAX8873/MAX8874
depends on the thermal resistance of the case and cir-

junction and ambient air, and the rate of air flow. The

in applications that include analog-to-digital converters
(ADCs) of greater than 12 bits, consider the ADC’s
power-supply rejection specifications (see the Output

Characteristics). For devices with lower output noise,

ing air, and θ is the thermal resistance of the chosen

package to the surrounding air.
The MAX8873/MAX8874 are designed to deliver low
dropout voltages and low quiescent currents in battery-
powered systems. Power-supply rejection is 62dB at
low frequencies and rolls off above 300Hz. As the fre-
quency increases above 20kHz, the output capacitor is
the major contributor to the rejection of power-supply
noise (see the Power-Supply Rejection Ratio vs.
Frequency graph in the Typical Operating
Characteristics).
The GND pin of the MAX8873/MAX8874 performs the
dual function of providing an electrical connection to
ground and channeling heat away. Connect the GND
pin to ground using a large pad or ground plane.
Reverse Battery Protection
The MAX8873/MAX8874 have a unique protection
scheme that limits the reverse supply current to less
than 1mA when either V or V
falls below ground.
SHDN
IN
When operating from sources other than batteries,
improve supply-noise rejection and transient response
by increasing the values of the input and output capac-
itors, and by using passive filtering techniques (see the
supply and load-transient responses in the Typical
Operating Characteristics).
The circuitry monitors the polarity of these two pins, dis-
connecting the internal circuitry and parasitic diodes
when the battery is reversed. This feature prevents the
device from overheating and damaging the battery.

When operating the MAX8873/MAX8874 with an input
voltage above 5.5V, a minimum load current of 20µA is
required to maintain regulation in preset voltage mode.
When setting the output with external resistors, the min-
imum current through the external feedback resistors
and load must be 30µA.
Load-Transient Considerations
The MAX8873/MAX8874 load-transient response
graphs (see Typical Operating Characteristics) show
two components of the output response: a DC shift of
the output voltage due to the different load currents
and the transient response. Typical overshoot for step
changes in the load current from 0mA to 50mA is
14mV. Increasing the output capacitor’s value and
decreasing its ESR attenuates transient spikes.

Capacitor Selection and
Regulator Stability
Input-Output (Dropout) Voltage
A regulator’s minimum input-output voltage differential
(or dropout voltage) determines the lowest usable sup-
ply voltage. In battery-powered systems, this will deter-
mine the useful end-of-life battery voltage. Because the
MAX8873/MAX8874 use a P-channel MOSFET pass
transistor, their dropout voltage is a function of RDS(ON)
multiplied by the load current (see Electrical
Characteristics).
Normally, use a 1µF capacitor on the input and a 1µF
capacitor on the output of the MAX8873/MAX8874.
Larger input capacitor values and lower ESR provide
better supply-noise rejection and transient response. A
higher-value input capacitor (10µF) may be necessary
if large, fast transients are anticipated and the device is
located several inches from the power source. Improve
load-transient response, stability, and power-supply
rejection by using large output capacitors. For stable
operation over the full temperature range, with load cur-
rents up to 120mA, a minimum of 1µF is recommended.
