MAX6469–MAX6484
The MAX6469–MAX6484 are low-dropout linear regula-
tors with a fully integrated microprocessor reset circuit.
Each is available with preset output voltages from +1.5V
to +3.3V in 100mV increments and delivers up to 300mA
of load current. These devices consume only 82µA of
supply current. The low supply current, low dropout volt-
age, and integrated reset functionality make these
devices ideal for battery-powered portable equipment.
The MAX6469–MAX6484 include a reset output that indi-
cates when the regulator output drops below standard
microprocessor supply tolerances (-7.5% or -12.5% of
nominal output voltage). This eliminates the need for an
external microprocessor supervisor, while ensuring that
supply voltages and clock oscillators have stabilized
before processor activity is enabled. Push-pull and open-
drain active-low reset outputs are available, with reset
timeout periods of 2.5ms, 20ms, 150ms, or 1200ms (min).
The MAX6469/MAX6470/MAX6473–MAX6478/MAX6481–
MAX6484 also have a shutdown feature that reduces the
supply current to 0.1µA (typ). The MAX6471–MAX6474/
MAX6479–MAX6482 offer a manual reset input to assert a
microprocessor reset while the regulator output is within
specification. The MAX6475/MAX6476/MAX6483/
MAX6484 feature a remote feedback sense pin for use
with an external NPN transistor for higher-current applica-
tions. The MAX6469–MAX6476 are available in 6-pin
SOT23 and 8-pin TDFN packages. The MAX6477–
MAX6484 are available in a 3
×
3 chip-scale package
(UCSP™). All devices are specified for operation from
-40°C to +85°C.

Note:
The first “_ _”are placeholders for the output voltage levels
of the devices. Desired output voltages are set by the suffix found
in the Output Voltage Suffix Guide (Table 1). The third “_” is a
placeholder for the reset threshold accuracy. Desired reset
threshold accuracy is set by the suffix found in the Reset
Threshold Accuracy Guide (Table 2). The “_” following the D is a
placeholder for the reset timeout delay time. Desired reset timeout
delay time is set by the suffix found in the Reset Timeout Delay
Guide (Table 3). For example, the MAX6481BL30BD4-T has a
3.0V output voltage, 12.5% reset threshold tolerance, and a
1200ms (min) reset timeout delay. Sample stock is generally avail-
able on standard versions only (Table 4). Standard versions
require a minimum order increment of 2.5k units. Nonstandard
versions must be ordered in 10k-unit increments. Contact factory
for availability.
