General Description
The MAX6329/MAX6349 are low-dropout, micropower
linear voltage regulators with integrated microproces-
sor reset circuits. Each is available with preset +3.3V,
+2.5V, +1.8V, or adjustable output voltages and can
deliver up to 150mA load current. Employing internal P-
channel MOSFET pass transistors, the devices con-
sume only 25µA supply current, independent of the
device load. The low supply current, low dropout volt-
age, and integrated reset functionality make these
devices ideal for battery powered portable equipment.
The MAX6329/MAX6349 include an internal reset circuit
that indicates when the regulator output drops below
standard microprocessor supply tolerances (-5% or
-10%). The reset output remains asserted for 100ms
(min) after the regulator output exceeds the selected
reset threshold, ensuring that supply voltages and clock
oscillators have stabilized before processor activity is
enabled. Reset outputs are available in push-pull (active-
low or -high) and open-drain (active-low) options. The
internal reset circuit replaces external microprocessor
supervisors or RC-based reset time delays.
The MAX6329/MAX6349 are optimized for use with a
1µF (min) output capacitor. The regulator output volt-
age is adjustable with an external resistor-divider net-
work at SET (reset threshold voltages track the desired
output voltage). Each device includes thermal shut-
down protection, output short-circuit protection, and
reverse leakage protection. The MAX6329 includes a
shutdown feature to reduce regulator current below
1µA (max) and the MAX6349 offers a manual reset
input to assert a microprocessor reset while the regula-
tor output is within specification.

Detailed Description
The MAX6329/MAX6349 are low-dropout, low-quies-
cent current linear regulators with integrated micro-
processor reset circuits. The devices drive loads up to
150mA and are available with preset output voltages of
+3.3V, +2.5V, or +1.8V. The internal reset circuit moni-
tors the regulator output voltage and asserts the reset
output when the regulator output is below the micro-
processor supply tolerance.
Regulator
The regulator core operates with an input voltage range
of +2.5V to +5.5V. The output voltage is offered with
three fixed voltage options (+3.3V, +2.5V, and +1.8V) for
the MAX6329 and MAX6349. Enable the fixed voltage
output by connecting SET to ground. The
MAX6329/MAX6349 offer an adjustable output voltage
that is implemented with an external resistor-divider net-
work connected to OUT, SET, and GND (Figure 1). SET
must be connected to either GND or the external divider.
The MAX6329/MAX6349 automatically determine the
feedback path depending on the voltage seen at SET.
Featured characteristics include ultra-low quiescent cur-
rent and low dropout voltage. The Typical Operating
Circuit shows a typical connection for the MAX6329.
OUT is an internally regulated low dropout (LDO) linear
regulator that powers a microprocessor.
Reset Circuit
The reset supervisor circuit is fully integrated in the
MAX6329/MAX6349 and uses the same reference volt-
age as the regulator. Two supply tolerance reset thresh-
olds, -5% and -10%, are provided for each type of
device:

Pin Description
PIN NAME DESCRIPTION
1 IN Regulator Input. Supply voltage can range from +2.5V to +5.5V.
2 GND Ground. This pin also functions as a heatsink. Solder to large pads or the circuit board ground plane to
maximize thermal dissipation.
SHDN (MAX6329 Only) Active-Low Shutdown Input. A logic low reduces the supply current to < 1µA. Connect
3MR
(MAX6349 Only) Active-Low Manual Reset Input. A logic low forces a reset. Reset remains asserted for
the duration of the reset timeout period after MR transitions from low to high. Leave unconnected or
connect to VOUT if not used. MR has an internal pullup resistor of 20kΩ (typ) to OUT.
RESET
Active-Low Reset Output. RESET remains low while VOUT is below the reset threshold or while MR is
held low. RESET remains low for the duration of the reset timeout period after the reset conditions are
terminated.

RESET
Active-High Reset Output. RESET remains high while VOUT is below the reset threshold or while MR is
held low. RESET remains high for the duration of the reset timeout period after the reset conditions are
terminated.
5 SET
Feedback Input for Setting the Output Voltage. Connect to GND to set the output voltage to the preset
fixed value (+3.3V, +2.5V, or +1.8V). Connect to an external resistor-divider network for adjustable
output operation.
6 OUT Regulator Output. Fixed (+3.3V, +2.5V, or +1.8V) or adjustable (+1.23V to +5.0V). Sources up to

5% reset: Reset does not assert until the regulator out-
put voltage is at least -5% out of tolerance and always
asserts before the regulator output voltage is -10% out of
tolerance.
10% reset: Reset does not assert until the regulator
output voltage is at least -10% out of tolerance and
always asserts before the regulator output voltage is
-15% out of tolerance.
Reset Output
A µP’s reset input starts the µP in a known state. The
MAX6329/MAX6349 µP supervisory circuits assert a
reset during power-up, power-down, and brownout
conditions. Reset is guaranteed to be logic high or low
depending on the device chosen (see Selector Guide).
RESET or RESET asserts when VOUT is below the reset
threshold and for at least 100ms (tRP) after VOUT rises
above the reset threshold. RESET or RESET also
asserts when MR is low (MAX6349).
Shutdown (MAX6329 Only)
SHDN allows for the regulator to shutdown thereby
reducing the total IIN consumption of the device. The
MAX6329 provides a digitally controlled active-low
shutdown function. In shutdown mode the pass transis-
tor, control circuit, reference, and all biases turn off,
reducing the supply current to below 1µA. Connect
SHDN to IN for normal operation.
Manual Reset Input (MAX6349 Only)
Many µP-based products require manual reset capabil-
ity, allowing the operator, a test technician, or external
logic circuitry to initiate a reset. For the MAX6349, a

logic low on MR asserts reset while the regulator is still
within tolerance.
Reset remains asserted while MR is low and for the
reset timeout period (100ms min) after MR returns high.
The MR input has an internal pullup of 20kΩ(typ) to
OUT. This input can be driven with TTL/CMOS logic
levels or with open-drain/collector outputs. Connect a
normally open momentary switch from MR to GND to
create a manual reset function; external debounce cir-
cuitry is not required. If MR is driven from long cables
or the device is used in a noisy environment, connect a
0.1µF capacitor from MR to GND to provide additional
noise immunity.
Reverse Leakage Protection
An internal circuit monitors the input and output volt-
ages. When the output voltage is greater than the input
voltage, the internal pass transistor and parasitic
diodes turn off. OUT powers the device. There is no
leakage path from OUT to IN. Therefore, the output can
be powered from an auxiliary supply such as a backup
battery without any need for additional blocking diodes.
Current Limit
The MAX6329/MAX6349 include a current limiter that
monitors and controls the pass transistor’s gate voltage,
limiting the output current to 350mA (typ). The output can
be shorted to ground for an indefinite period without
damaging the part.
Thermal Overload Protection
When the junction 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 sensor will turn the pass transistor on again
after the IC’s junction temperature cools by 20°C,
resulting in a pulsed output during continuous thermal-
overload conditions. Thermal overload protection is
designed to protect the MAX6329/MAX6349 in the
event of fault conditions. For continuous operation, do
not exceed the absolute maximum junction temperature
rating of TJ= +150°C.
Operating Region and Power Dissipation
The MAX6329/MAX6349s’ maximum power dissipation
depends on the thermal resistance of the case and cir-
cuit board, the temperature difference between the die
junction and the ambient air, and the rate of airflow.
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
die junction and the surrounding air, θJB (or θJC) is the
thermal resistance of the package, and θBA is the ther-
mal resistance through the printed circuit board, copper
traces, and other materials to the surrounding air.
The MAX6329/MAX6349s’ ground pin (GND) performs
the dual function of providing an electrical connection
to the system ground and channeling heat away.
Connect GND to the system ground using a large pad
or ground plane.
Applications Information
Output Voltage Selection
The MAX6329/MAX6349 feature dual mode operation:
they operate in either a preset voltage mode or an
adjustable mode. In preset voltage mode, internal
feedback resistors set the MAX6329/MAX6349 to
+3.3V, +2.5V, or +1.8V (see Selector Guide). Select this
mode by connecting SET to ground. In adjustable
mode, select an output between 1.23V to 5.0V using
two external resistors connected as a voltage divider to
SET (Figure 1). The output voltage is set by the following
equation:
VOUT = VSET (1 + R1/R2)
where VSET = 1.23V. To simplify resistor selection:
R1 = R2 (VOUT/VSET - 1)
Choose R2 ≥100kΩto optimize power consumption,
accuracy, and high-frequency power-supply rejection.
Since the VSET tolerance is typically less than ±30mV,
the output can be set using fixed resistors instead of
variable resistors. In preset voltage mode, impedance
between SET and ground should be less than 50kΩ.

Capacitor Selection and
Regulator Stability
For stable operation over the full temperature range
and with load currents up to 150mA, use a 1µF (min)
output capacitor. To reduce noise and improve load
transient response, stability, and power-supply rejec-
tion, use large output capacitor values such as 10µF.
Note that some ceramic dielectrics exhibit large capac-
itance and ESR variation with temperature. With
dielectrics such as Z5U and Y5V, it may be necessary
to use 2.2µF or more to ensure stability at temperatures
below -10°C. With X7R or X5R dielectrics, 1µF should
be sufficient at all operating temperatures. A graph of
the Region of Stable COUT ESR vs. Load Current is
shown in the Typical Operating Characteristics.
To improve power-supply rejection and transient
response use a 1µF capacitor between IN and GND.
Input-Output (Dropout) Voltage
A regulator’s minimum input-output voltage differential
(or dropout voltage) determines the lowest useable
supply voltage. In battery powered systems, this will
determine the useful end-of-life battery voltage. Since
the MAX6329/MAX6349 use a P-channel MOSFET pass
transistor, their dropout voltage is a function of RDS(ON)
multiplied by the load current (see Electrical
Characteristics).
Negative Going OUT Transients
These supervisors are relatively immune to short-dura-
tion, negative going OUT transients. The Typical
Operating Characteristics section shows a graph of the
Maximum Transient Duration vs. Reset Threshold
Overdrive for which reset is not asserted. The graph
was produced using negative going OUT transients
starting at OUT and ending below the reset threshold
by the magnitude indicated (Reset Threshold
Overdrive). The graph shows the maximum pulse width
that a negative going OUT transient can typically have
without triggering a reset pulse. As the amplitude of the
transient increases (i.e., goes further below the reset
threshold), the maximum allowable pulse width
decreases. Typically, an OUT transient that goes only
10mV below the reset threshold and lasts for 75µs will
not trigger a reset pulse.
