The
MAX6791–MAX6796
ultra-low-quiescent-
current, single/dual-output linear regulators are ideal for
automotive applications. The devices offer a wide 5V to
72V operating input range, allowing them to withstand
automotive load-dump conditions while consuming only
68μA. The MAX6791–MAX6794 are dual-output regulators
capable of supplying up to 150mA per output. The
MAX6795/MAX6796 offer a single output capable of
delivering up to 300mA. These devices offer standard
output-voltage options (5V, 3.3V, 2.5V, or 1.8V) and
can be adjusted to any voltage from 1.8V to 11V. The
MAX6791–MAX6794 also offer a fixed 5V output.
All devices feature a push-pull or open-drain, active-
low
RESET
output with a fixed output reset threshold
that is 92.5%/87.5% of the regulator output OUT/OUT1.
The reset output asserts low when OUT/OUT1 drops
below the reset threshold and remains low for the fixed
or capacitor-adjustable reset timeout period after OUT/
OUT1 exceeds the reset threshold.
The MAX6791–MAX6796 provide a watchdog input that
monitors a pulse train from the microprocessor (μP) and
generates reset pulses if the watchdog input remains high
or low for a duration longer than the watchdog timeout
period. All devices are available with either a fixed watch-
dog timeout period of 280ms (min) or a period adjustable
with an external capacitor. The MAX6791/MAX6792
feature a windowed watchdog timeout period with selectable
window ratio. The watchdog feature can be disabled.
The MAX6791–MAX6794 provide dual enable inputs
(ENABLE1 and ENABLE2) that control each regulator
independently. The single-output MAX6795/MAX6796
feature one enable input (ENABLE).
All devices include a hold input (HOLD) that aids the
implementation of a self-holding circuit without requiring
external components. Once the regulator is enabled,
setting
HOLD
low forces the regulator to remain on even
if ENABLE/ENABLE1 is subsequently set low. Releasing
HOLD
shuts down the regulator.
The MAX6791–MAX6796 are available in a small,
thermally enhanced TQFN package. The 5mm x 5mm
package dissipates up to 2.7W, supporting continuous
regulator operation during high ambient temperatures,
high battery voltage, and high load-current conditions.
The MAX6791–MAX6796 are specified for a -40°C to
+125°C operating temperature range.

+Denotes lead-free package.
For tape-and-reel, add a T after the “+.” Tape-and-reel are
offered in 2.5k increments. The first placeholder “_” designates
preset output-voltage option and preset reset threshold level;
see Table 1. The second placeholder “_” designates the reset
timeout period; see Table 2. For example, the MAX6791TPSD3+
indicates a 3.3V output voltage with a reset threshold of 87.5%
at nominal voltage and a 50ms reset timeout period. Samples
are generally held in stock. Nonstandard versions require a 2.5k
minimum order quantity.
