150mA, SOT23, Low-Dropout Linear Regulators
with Internal Microprocessor Reset Circuit
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-

These parts offer a choice of regulator/reset voltages and reset
outputs. From the Selector Guide, insert the desired suffix let-
ters into the blanks to complete the part number. Each device
is available in nine standard versions. Sample stock is general-
ly held on standard versions only (see Standard Versions
table). Standard versions have an order increment requirement
of 2500 pieces. Nonstandard versions have an order increment
requirement of 10,000 pieces. Contact factory for availability of
nonstandard versions.
