150mA, SOT23, Low-Dropout Linear Regulators

with Internal Microprocessor Reset Circuit

General Description

Features

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.

o ꢄmall Output Capaꢁꢅtor (1µF mꢅn ꢁeramꢅꢁ or

tantalum)

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.

o Regulator ꢄꢃutdown Input (MAX6329) or Manual

o 6-Pꢅn ꢄOT23 Paꢁkage

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.

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.
