    General Description
    The MAX6765–MAX6774 are low-quiescent-current, high-
    voltage linear regulators that operate from 4V to 72V and
    deliver up to 100mA of load current. These low-power
    devices consume only 31μA of quiescent current, making
    them ideal for always-on automotive modules. These
    devices are offered with fixed standard output options of
    5.0V, 3.3V, 2.5V, and 1.8V, or can be adjusted from 1.8V
    to 11V with two external resistors.
    The MAX6765–MAX6774 feature a push-pull or open-
    drain, active-low 
    RESET
     output with either fixed or
    adjustable thresholds. Whenever the regulator’s output
    falls below the reset threshold, the 
    RESET
     output asserts
    and remains asserted for at least the minimum reset
    timeout period after the output voltage exceeds its
    threshold. The minimum reset timeout period is offered
    with fixed values from 75μs to 200ms or can be adjusted
    externally with a small capacitor.
    These devices provide three regulator enable modes to
    accommodate several power-on schemes. The
    MAX6765/MAX6766/MAX6769/MAX6770/MAX6773/
    MAX6774 feature a single traditional enable input
    (ENABLE) to turn on and off the regulator. The
    MAX6771/MAX6772 provide dual enable inputs
    (ENABLE1 and ENABLE2) to turn on and off the regulator
    either through an ignition switch or a bus transceiver. The
    MAX6767/MAX6768 provide a hold input (
    HOLD
    ) in addi-
    tion to the enable input to allow for the implementation of a
    self-holding circuit without requiring external components.
    Setting 
    HOLD
     low after enabling the regulator forces the
    regulator to remain on even if ENABLE is subsequently
    set low. Releasing 
    HOLD
     shuts down the regulator.
    The MAX6773/MAX6774 also include a watchdog input
    that monitors a pulse train from the microprocessor (μP)
    and generates a reset pulse if the watchdog input
    remains high or low for a duration longer than the 1.6s
    (typ) watchdog timeout period.
    The MAX6765–MAX6774 are available in a small, ther-
    mally enhanced 3mm x 3mm TDFN package that can
    dissipate up to 1.951W, thereby supporting continuous
    regulator operation during high ambient temperatures,
    high battery voltage, and high load-current conditions.
    The MAX6765–MAX6774 are fully specified for a -40°C to
    +125°C operating temperature range.

    The first “_” is a placeholder for the voltage output and reset
    threshold. The 2nd “_” designates the fixed reset-timeout option.
    See Tables 1 and 2 for details. For example, the MAX6765TTLD4
    has a 5V output, a reset threshold of 4.65V, and a 200ms typical
    reset timeout.
