General Description
The MAX8880/MAX8881 are ultra-low supply current,
low-dropout linear regulators, capable of delivering up
to 200mA. They are designed for battery-powered
applications where reverse battery protection and long
battery life are critical.
These regulators’ low 3.5µA supply current extends bat-
tery life in applications with long standby periods. Unlike
PNP-based designs, a 2ΩPMOS device maintains ultra-
low supply current throughout the entire operating range
and in dropout. The parts are internally protected from
output short circuits, reverse battery connection, and
thermal overload. An internal power-OK (POK) com-
parator indicates when the output is out of regulation.
The MAX8880 output is adjustable from 1.25V to 5V
using an external resistor-divider. The MAX8881 pro-
vides only factory-preset output voltages of 1.8V, 2.5V,
3.3V, or 5V (see Ordering Information). The devices are
available in 6-pin SOT23 and 6-pin TDFN packages.

Detailed Description
The MAX8880/MAX8881 are low-dropout, low-quies-
cent current linear regulators designed primarily for
battery-powered applications (Figure 1). The MAX8880
provides an adjustable output voltage from 1.25V to 5V
using an external resistor-divider. The MAX8881 is
available in factory preset output voltages of 1.8V, 2.5V,
3.3V, and 5V. Both devices have a +1.25V reference,
error amplifier, MOSFET driver, and P-channel pass
transistor (Figure 2).
Low-Dropout Regulator
The 1.25V reference is connected to the error amplifi-
er’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 and applies the appropriate drive to the P-
channel pass transistor. If the feedback voltage is lower
than the reference voltage, the pass-transistor gate is
pulled lower, allowing more current to pass, increasing
the output voltage. If the feedback voltage is higher
than the reference voltage, the pass-transistor gate is
driven higher, allowing less current to pass to the out-
put. The output voltage is fed back through either an
internal resistor voltage divider by externally connect-
ing FB to OUT (MAX8881), or an external resistor net-
work connected to FB (MAX8880). Additional blocks
include an output current limiter, reverse battery pro-
tection, a thermal sensor, shutdown logic, and a POK
comparator to indicate when the output is out of regula-
tion (Figure 2).
Internal P-Channel Pass Transistor
The MAX8880/MAX8881 feature a 2ΩP-channel MOS-
FET pass transistor. This provides advantages over
similar designs using PNP pass transistors, including
longer battery life. The P-channel MOSFET requires no
base drive, which reduces quiescent current consider-
ably. PNP-based regulators waste considerable current
in dropout when the pass transistor saturates. They
also use high base-drive currents under large loads.
The MAX8880/MAX8881 do not suffer from these prob-
lems and consume only 3.5µA of supply current (see
Typical Operating Characteristics).
Dropout Voltage
A regulator’s minimum input-output differential (or
dropout voltage) determines the lowest usable supply
voltage. In battery-powered systems, this determines
the useful end-of-life battery voltage. Because the
MAX8880/MAX8881 use a P-channel MOSFET pass
transistor, their dropout voltage is RDS(ON) (2Ω) multi-
plied by the load current (see Electrical Characteristics).

Reverse Battery Protection
The MAX8880/MAX8881 have a unique protection
scheme that limits the reverse supply current to less
than 1mA when VIN is forced below ground. The circuit
monitors the polarity of IN, disconnecting the internal
circuitry and parasitic diodes when the battery is
reversed. This feature prevents the device from electri-
cal stress and damage when the battery is connected
backwards. If reverse battery protection is needed,
drive SHDN through a 100kΩresistor.
Current Limiting
The MAX8880/MAX8881 include a current limiter. When
the output is shorted to ground, drive to the output
PMOS is limited. The output can be shorted to ground
without damage to the part.
Thermal Overload Protection
Thermal overload protection limits total power dissipa-
tion in the MAX8880/MAX8881. When the internal junc-
tion temperature exceeds TJ= +160°C, the thermal
sensor signals the shutdown logic, turning off the pass
transistor and allowing the IC to cool. The thermal sen-
sor turns the pass transistor on again after the IC’s
junction temperature cools by 15°C, resulting in a
pulsed output during continuous thermal-overload con-
ditions.
Thermal-overload protection is designed to protect the
MAX8880/MAX8881 in the event of fault conditions. For
continuous operation, do not exceed the absolute maxi-
mum junction temperature rating of TJ(MAX) = +150°C.
Operating Region and Power Dissipation
The MAX8880/MAX8881’s maximum power dissipation
depends on the thermal resistance of the case and cir-
cuit board, the temperature difference between the die
junction and ambient air, and the rate of airflow. The
power dissipation in the device is P = IOUT (VIN -
VOUT). The maximum power dissipation allowed is:

ture, θJC is the thermal resistance from the junction to
the case, and θCA is the thermal resistance from the
case through the PC board, copper traces, and other
materials to the surrounding air.
POK Output
The open-drain POK output is useful as a simple error
flag, as well as a delayed reset output. POK sinks cur-
rent when the output voltage is 10% below the regula-
tion point. Connect POK to OUT through a high-value
resistor for a simple error flag indicator. Connect a
capacitor in parallel with the resistor to produce a
delayed POK signal (delay set by the RC time con-
stant). POK is low during out of regulation or in shut-
down and is high impedance during normal operation.
Applications Information
Capacitor Selection and Regulator
Stability
The MAX8880/MAX8881 are designed to be stable with
an output filter capacitor as low as 1µF and an ESR as
high as 1Ω. For general purposes, use a 1µF capacitor
on the device’s input and a 4.7µF capacitor on the out-
put. Larger input capacitor values and lower ESR pro-
vide better supply-noise rejection and transient
response. Use 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. Use large output capacitors to improve load-
transient response, stability, and power-supply rejec-
tion. Note that some ceramic dielectric materials (e.g.,
Z5U and Y5V) exhibit a large temperature coefficient for
both capacitance and ESR, and a larger output capaci-
tance may be needed to ensure stability at low tempera-
tures. A 4.7µF output capacitor with X7R or X5R
dielectrics should be sufficient for stable operation over
the full temperature range, with load currents up to
200mA. For load currents up to 40mA, 1µF is accept-
able. A graph of the Region of Stable Cout ESR vs.
Output Current is shown in the Typical Operating
Characteristics.
Output Voltage Selection
The MAX8881 features a preset output voltage. Internal
precision feedback resistors set the MAX8881EUT18 out-
put to 1.8V, the MAX8881EUT25 output to 2.5V, the
MAX8881EUT33 output to 3.3V, and the MAX8881EUT50
output to 5V. Connect the MAX8881’s FB to OUT for
proper operation.
The MAX8880 features an adjustable output voltage
from 1.25V to 5.5V, using two external resistors con-
nected as a voltage-divider to FB (Figure 3).
The output voltage is set by the following equation:
where typically VFB = 1.257V. Choose R4 = 1.2MΩto
optimize quiescent current, accuracy, and high-fre-
quency power-supply rejection. To simplify resistor
selection:
The total current through the external resistive feedback
and load resistors should be greater than 1µA. Since the
VFB tolerance is typically less than ±1.5%, the output
can be set using fixed resistors instead of trim pots.
Power-Supply Rejection and Operation
from Sources Other than Batteries
The MAX8880/MAX8881 are designed to deliver low-
dropout voltages and low quiescent currents in battery-
powered systems. Power-supply rejection is -66dB at
low frequencies and rolls off with frequencies above
100Hz. At high frequencies, the output capacitor is the
major contributor to the rejection of power-supply noise
(see Power-Supply Rejection Ratio vs. Frequency in the
Typical Operating Characteristics).
When operating from sources other than batteries,
improve supply-noise rejection and transient response
by increasing the value of the input and output capaci-
tors and by using passive filtering techniques.
The MAX8880/MAX8881 load-transient response
graphs (see Typical Operating Characteristics) show
the output response due to changing load current.
Reduce overshoot by increasing the output capacitor’s
value up to 10µF and by reducing its ESR.
