NAME

HOLD
Active-Low Regulator Hold Input. When
HOLD
is forced
low, OUT remains on even if ENABLE is pulled low. To
shut down the regulator, release
HOLD
after ENABLE is
pulled low. Connect
HOLD
to OUT or leave
unconnected if unused.
HOLD
is internally connected
to OUT through a 1.8μA current source.

SET
Feedback Input for Setting the Output Voltage. Connect
SET to GND to select the preset output voltage.
Connect to an external resistive divider for
adjustable output operation.

RESETIN
Adjustable Reset Threshold Input. Connect to a
resistive divider to set the desired threshold.

ENABLE1
Active-High Enable Input 1. Drive ENABLE1 high to turn
on the regulator. ENABLE1 is internally connected to
ground through a 0.6μA current sink.

ENABLE2
Active-High Enable Input 2. Drive ENABLE2 high to turn
on the regulator. ENABLE2 is internally connected to
ground through a 0.6μA current sink.

WDI
Watchdog Timer Input. If WDI remains high or low for
longer than the watchdog timeout period, the
internal watchdog timer expires and the reset output
asserts for the reset timeout period. The internal
watchdog timer clears whenever a reset is asserted or
WDI sees a rising or falling edge. The watchdog timer
cannot be disabled. Do not leave WDI unconnected.

—
Exposed Paddle. EP is internally connected to GND.
Connect EP to the ground plane to provide a low
thermal-resistance path from the IC junction to the PCB.
Do not use as the electrical connection to GND.
Detailed Description
The MAX6765–MAX6774 low-quiescent-current, high-
voltage linear regulators operate from a 4V to 72V input
voltage and deliver more than 100mA of load current.
The MAX6765–MAX6774 include an integrated μP reset
circuit that monitors the regulator output voltage and
asserts a reset output when OUT falls below a threshold
limit, and includes an internally fixed or adjustable reset
timeout using a capacitor from TIMEOUT to ground. All
devices are available in a preset output-voltage option of
+1.8V, +2.5V, +3.3V, and +5V. The output voltage of the
MAX6767–MAX6774 is adjustable from +1.8V to +11V
using a resistive divider at SET. The MAX6773/MAX6774
include a watchdog timer (WDI) with a 1.6s (typ) watch-
dog timeout period. The MAX6769/MAX6770 feature an
adjustable reset threshold using a resistive divider
between the monitored voltage, RESETIN, and GND; see
the
Functional Diagrams
.
The MAX6771/MAX6772 provide dual enable inputs
(ENABLE1 and ENABLE2) to turn on and off the regula-
tor either through an ignition switch or a bus transceiver.
