__________________General Description
The MAX8877/MAX8878 low-noise, low-dropout linear
regulators operate from a 2.5V to 6.5V input and deliver
up to 150mA. These devices are pin-compatible with
the industry-standard '2982 and offer an improved
dropout voltage. Typical output noise is 30µVRMS, and
typical dropout is only 165mV at 150mA. The output
voltage is preset to voltages in the range of 1.5V to
5.0V, in 100mV increments.
Designed with an internal P-channel MOSFET pass
transistor, the MAX8877/MAX8878 maintain a low
100µA supply current, independent of the load current
and dropout voltage. Other features include a 10nA
logic-controlled shutdown mode, short-circuit and ther-
mal-shutdown protection, and reverse battery protec-
tion. The MAX8878 also includes an auto-discharge
function, which actively discharges the output voltage
to ground when the device is placed in shutdown. Both
devices come in regular and thin 5-pin SOT23 pack-
ages.

MAX8877/MAX8878
_______________Detailed Description
The MAX8877/MAX8878 are low-noise, low-dropout,
low-quiescent-current linear regulators designed pri-
marily for battery-powered applications. The parts are
available with preset output voltages ranging from 1.5V
to 5V, in 100mV increments. These devices can supply
loads up to 150mA. As illustrated in Figure 1, the
MAX8877/MAX8878 consist of a 1.25V reference, error
amplifier, P-channel pass transistor, and internal feed-
back voltage divider.
The 1.25V bandgap reference is connected to the error
amplifier’s inverting input. The error amplifier compares
this reference with the feedback voltage and amplifies
the difference. If the feedback voltage is lower than the
reference voltage, the pass-transistor gate is pulled
lower, which allows more current to pass to the output
and increases the output voltage. If the feedback volt-
age is too high, the pass-transistor gate is pulled up,
allowing less current to pass to the output. The output
voltage is fed back through an internal resistor voltage
divider connected to the OUT pin.
An external bypass capacitor connected to the BP pin
reduces noise at the output. Additional blocks include a
current limiter, reverse battery protection, thermal sen-
sor, and shutdown logic. The MAX8878 also includes
an auto-discharge function, which actively discharges
the output voltage to ground when the device is placed
in shutdown mode.

PIN NAME FUNCTION
1IN
Regulator Input. Supply voltage can range from 2.5V to 6.5V. Bypass with a 1µF capacitor to GND
(see Capacitor Selection and Regulator Stability section).
2 GND Ground. This pin also functions as a heatsink. Solder to a large pad or the circuit-board ground
plane to maximize power dissipation.
3SHDN Active-Low Shutdown Input. A logic low reduces the supply current to 10nA. On the MAX8878, a
logic low also causes the output voltage to discharge to GND. Connect to IN for normal operation.
4BP
Reference-Noise Bypass. Bypass with a low-leakage, 0.01µF ceramic capacitor for reduced noise at
the output.
5 OUT Regulator Output. Sources up to 150mA. Bypass with a 1µF (<0.2 typical ESR) capacitor to GND
for VOUT 2.5V and 3.3µF for VOUT < 2.5V.
Output Voltage
The MAX8877/MAX8878 are supplied with factory-set
output voltages from 1.5V to 5.0V, in 100mV increments.
Except for the MAX887_EUK29 and the MAX887_EUK32
(which have an output voltage preset at 2.84V and
3.15V, respectively), the two-digit suffix allows the cus-
tomer to choose the output voltage in 100mV increments.
For example, the MAX8877EUK33 has a preset output
voltage of 3.3V (see Expanded Ordering Information).
Internal P-Channel Pass Transistor
The MAX8877/MAX8878 feature a 1.1typical
P-channel MOSFET pass transistor. This provides sever-
al advantages over similar designs using PNP pass tran-
sistors, including longer battery life. The P-channel
MOSFET requires no base drive, which reduces quies-
cent current considerably. PNP-based regulators waste
considerable current in dropout when the pass transistor
saturates. They also use high base-drive currents under
large loads. The MAX8877/MAX8878 do not suffer from
these problems and consume only 100µA of quiescent
current whether in dropout, light-load, or heavy-load
applications (see the Typical Operating Characteristics).
Current Limit
The MAX8877/MAX8878 include a current limiter, which
monitors and controls the pass transistor’s gate voltage,
limiting the output current to 390mA. For design purposes,
consider the current limit to be 160mA minimum to 500mA
maximum. The output can be shorted to ground for an
indefinite amount of time without damaging the part.
Thermal-Overload Protection
Thermal-overload protection limits total power dissipa-
tion in the MAX8877/MAX8878. When the junction tem-
perature exceeds TJ= +155°C, the thermal sensor
signals the shutdown logic, turning off the pass transis-
tor and allowing the IC to cool. The thermal sensor will
turn the pass transistor on again after the IC’s junction
temperature cools by 15°C, resulting in a pulsed output
during continuous thermal-overload conditions.
Thermal-overload protection is designed to protect the
MAX8877/MAX8878 in the event of fault conditions. For
continual operation, do not exceed the absolute maxi-
mum junction-temperature rating of TJ= +150°C.
Operating Region and Power Dissipation
The MAX8877/MAX8878’s maximum power dissipation
depends on the thermal resistance of the case and circuit
board, the temperature difference between the die junc-
tion and ambient air, and the rate of air flow. The power
dissipation across the device is P = IOUT (VIN - VOUT).
The maximum power dissipation is:
PMAX = (TJ- TA) / (θJB +θBA)
where TJ- TAis the temperature difference between
the MAX8877/MAX8878 die junction and the surround-
ing air, θJB (or θJC) is the thermal resistance of the
package, and θBA is the thermal resistance through the
printed circuit board, copper traces, and other materi-
als to the surrounding air.
The GND pin of the MAX8877/MAX8878 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 MAX8877/MAX8878 have a unique protection
scheme that limits the reverse supply current to 1mA
when either VIN or VSHDN falls below ground. Their cir-
cuitry monitors the polarity of these two pins and discon-
nects the internal circuitry and parasitic diodes when the
battery is reversed. This feature prevents device damage.
Noise Reduction
An external 0.01µF bypass capacitor at BP, in conjunc-
tion with an internal 200kresistor, creates a 80Hz low-
pass filter for noise reduction. The MAX8877/MAX8878
exhibit 30µVRMS of output voltage noise with CBP =
0.01µF and COUT = 10µF. This is negligible in most
applications. Start-up time is minimized by a power-on
circuit that pre-charges the bypass capacitor. The
Typical Operating Characteristics section shows
graphs of Noise vs. BP Capacitance, Noise vs. Load
Current, and Output Noise Spectral Density.
____________Applications Information
Capacitor Selection and
Regulator Stability
Normally, use a 1µF capacitor on the MAX8877/
MAX8878’s input and a 1µF to 10µF capacitor on the out-
put. Larger input capacitor values and lower ESRs pro-
vide better supply-noise rejection and line-transient
response. Reduce noise and improve load-transient
response, stability, and power-supply rejection by using
large output capacitors. For stable operation over the full
temperature range and with load currents up to 150mA, a
1µF (min) ceramic capacitor is recommended for VOUT
2.5V and 3.3µF and for VOUT < 2.5V.
Note that some ceramic dielectrics exhibit large capaci-
tance and ESR variation with temperature. With
dielectrics such as Z5U and Y5V, it may be necessary to
increase the capacitance by a factor of 2 or more to
ensure stability at temperatures below -10°C. With X7R or
X5R dielectrics, 1µF should be sufficient at all operating
temperatures for VOUT 2.5V. A graph of the Region of

Stable COUT ESR vs. Load Current is shown in the
Typical Operating Characteristics.
Use a 0.01µF bypass capacitor at BP for low output volt-
age noise. Increasing the capacitance will slightly
decrease the output noise, but increase the start-up time.
Values above 0.1µF provide no performance advantage
and are not recommended (see Shutdown Exit Delay
graphs in the Typical Operating Characteristics).
PSRR and Operation from
Sources Other than Batteries
The MAX8877/MAX8878 are designed to deliver low
dropout voltages and low quiescent currents in battery-
powered systems. Power-supply rejection is 63dB at
low frequencies and rolls off above 10kHz. See the
Power-Supply Rejection Ratio Frequency graph in the
Typical Operating Characteristics.
When operating from sources other than batteries,
improved supply-noise rejection and transient response
can be achieved by increasing the values of the input
and output bypass capacitors, and through passive fil-
tering techniques. The Typical Operating Charac-
teristics show the MAX8877/MAX8878’s line- and load-
transient responses.
Load-Transient Considerations
The MAX8877/MAX8878 load-transient response
graphs (see Typical Operating Characteristics) show
two components of the output response: a DC shift
from the output impedance due to the load current
change, and the transient response. Typical transient
for a step change in the load current from 0mA to 50mA
is 12mV. Increasing the output capacitor’s value and
decreasing the ESR attenuates the overshoot.
Input-Output (Dropout) Voltage
For output voltage greater than the minimum input volt-
age (2.5V), the regulator’s minimum input-output volt-
age differential (or dropout voltage) determines the
lowest usable supply voltage. In battery-powered sys-
tems, this will determine the useful end-of-life battery
voltage. Because the MAX8877/MAX8878 use a P-
channel MOSFET pass transistor, their dropout voltage
is a function of drain-to-source on-resistance (RDS(ON))
multiplied by the load current (see Typical Operating
Characteristics).
