General Description
The MAX6765–MAX6774B 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, mak-
ing 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–MAX6774B 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/
MAX6773B/MAX6774/MAX6774B feature a single tradi-
tional enable input (ENABLE) to turn on and off the regu-
lator. 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/MAX6773B/MAX6774/MAX6774B 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) (MAX6773/MAX6774) or 50ms
(typ) (MAX6773B/MAX6774B) watchdog timeout period.
The MAX6765–MAX6774B 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–MAX6774B are fully specified for a -40°C
to +125°C operating temperature range.

Detailed Description
The MAX6765–MAX6774B 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–MAX6774B include an integrated µP
reset circuit that monitors the regulator output volt-
age 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 TIME-
OUT 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–MAX6774B is adjust-
able from +1.8V to +11V using a resistive divider at
SET. The MAX6773/MAX6774 include a watchdog timer
(WDI) with a 1.6s (typ) watchdog timeout period and the
MAX6773B/MAX6774B include a watchdog timer with
a 50ms (typ) watchdog 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.

Regulator
The regulator accepts an input voltage from +4V to +72V.
All of the devices feature fixed output-voltage options of
+1.8V, +2.5V, +3.3V, and +5V. The MAX6767–MAX6774B
feature an adjustable output voltage set with an external
resistive-divider network connected between OUT, SET,
and GND. See Figure 1.
Enable and Hold Inputs
(MAX6767/MAX6768)
The MAX6767/MAX6768 support two logic inputs,
ENABLE (active-high) and HOLD (active-low), making
these devices “automotive friendly.” For example, when
the ignition key signal drives ENABLE high, the regulator
turns on and remains on even if ENABLE goes low, as
long as HOLD is forced low and kept low before ENABLE
goes low. In this state, releasing HOLD turns the regulator
output (OUT) off. This feature makes it possible to imple-
ment a self-holding circuit without external components.
Forcing ENABLE low with HOLD high (or unconnected)
places the MAX6767/MAX6768 into shutdown mode,
drawing 3.3µA (typ) of supply current.
Table 3 shows the state of the regulator output with
respect to the voltage level at ENABLE and HOLD.
Connect HOLD to OUT or leave it unconnected to allow
the ENABLE input to act as a standard enable/shutdown
switch for the regulator output (OUT).
Reset Output
The reset output is typically connected to the reset input
of a µP. A µP’s reset input starts or restarts the µP in
a known state. The MAX6765–MAX6774B supervisory
circuits provide the reset logic to prevent code-execution
errors during power-up, power-down, and brownout con-
ditions (see the Typical Application Circuit). RESET
changes from high to low whenever the monitored volt-
age drops below the reset threshold voltages. Once the
monitored voltage exceeds its respective reset threshold
voltage(s), RESET remains low for the reset timeout
period, then goes high. See Table 1 and Table 2.
RESETIN Threshold (MAX6769/MAX6770)
The MAX6769/MAX6770 monitor the voltage on RESETIN
using an adjustable reset threshold (VRESETIN) set with
an external resistive voltage-divider and the internal reset
threshold (VTH). See Table 2.

Watchdog Timer (MAX6773/MAX6773B/
MAX6774/MAX6774B)
The MAX6773/MAX6774 include a watchdog timer that
asserts RESET if the watchdog input (WDI) does not
toggle within the watchdog timeout period, tWD (1.6s
(typ) for the MAX6773/MAX6774 and 50ms (typ) for the
MAX6773B/MAX6774B). RESET remains low for the
reset timeout period, tRP. If the watchdog is not updated
for lengthy periods of time, the reset output appears as
a pulse train, asserted for the reset timeout period and
deasserted for the watchdog timeout period, until WDI is
toggled again. When RESET asserts, it stays low for the
entire reset timeout period ignoring any WDI transitions.
To prevent the watchdog from asserting RESET, toggle
WDI with a valid rising or falling edge prior to tWD (min).
The watchdog counter clears when WDI toggles prior to
tWD or when RESET asserts. The watchdog resumes
counting after RESET deasserts. The watchdog timer
cannot be disabled.
Thermal Protection
When the junction temperature exceeds TJ = +160°C
(typ), an internal thermal sensor signals the shutdown
logic that turns off the pass transistor and allows the IC
to cool. The thermal sensor turns the pass transistor on
again after the IC’s junction temperature cools by 20°C
(typ), resulting in a cycled output during continuous ther-
mal-overload conditions. Thermal protection protects the
MAX6765–MAX6774B in the event of a fault condition.
Never exceed the absolute maximum junction tempera-
ture rating of TJ = +150°C. See Figures 3 and 4 for the
safe operating area.
Applications Information
Output-Voltage Selection
The MAX6767–MAX6774B feature dual-mode
operation and operate in either a preset or adjustable
voltage mode. In preset voltage mode, internal trimmed
feedback resistors set the internal linear regulator to
+1.8V, +2.5V, +3.3V, or +5V (see Table 2). Select preset-
voltage mode by connecting SET to ground. In adjustable
mode, select an output voltage between +1.8V and +11V
using two external resistors connected as a voltage-divid-
er to SET (see Figure 1). Set the output voltage using the
following equation:
VOUT = VSET (1 + R1/R2)
where VSET = 1.233V and the recommended value for R2
is 50k(maximum 100kΩ).
RESETIN Threshold Selection
The MAX6769/MAX6770 feature an adjustable reset
threshold to monitor the voltage on RESETIN using
a resistive divider between the monitored voltage,
RESETIN and GND. See Figure 2. Use the following
formula to set the desired reset threshold:
VMON = VTH (1 + R3/R4)
where VTH is 1.085V for the M/S/Y/V versions and 1.147V
for the L/T/Z/W versions.

Available Output-Current Calculation
The MAX6765–MAX6774B provide up to 100mA of load
current. Package power dissipation limits the amount
of output current available for a given input/output volt-
age and ambient temperature. Figures 3 and 4 depict
the maximum power dissipation curve for the MAX6765/
MAX6766 and MAX6767–MAX6774B, respectively. The
graph assumes that the exposed metal pad of the device
package is soldered to a solid 1in2 section of 2oz.
PCB copper (JESD51-3 AND JESD51-5). Use Figure
4 to determine the allowable package dissipation for a
given ambient temperature. Alternately, use the following
formula to calculate the allowable package dissipation:
PDMAX = Max. Power Dissip = 1.951W, for TA +70°C
PDMAX = Max. Power Dissip = [1.9W - 0.0244W x
(TA - 70°C)], for +70°C < TA+125°C
where 0.0244W is the MAX6767–MAX6774B package
thermal derating in W/°C and TA is the ambient tempera-
ture in °C, under the same conditions used for Figure 4.
After determining the allowable package dissipation,
calculate the maximum output current using the following
formula:
PD < PDMAX where PD = [(VIN - VOUT) x IOUT]
Also, IOUT should be 100mA in any case.
Selecting Timeout Capacitor
The reset timeout period is adjustable to accommodate a
variety of µP applications. Adjust the reset timeout period
by connecting a capacitor between TIMEOUT and GND.
tRP = CTIMEOUT x 1.22 x 106 (L/M/T/S options)
tRP = CTIMEOUT x 1.17 x 106Ω (V/W/Y/Z options)
where tRP is in seconds and CTIMEOUT is in Farads.
Connect TIMEOUT to OUT to select the internally
fixed timeout period. CTIMEOUT must be a low-leakage
(< 10nA) type capacitor. Ceramic capacitors are
recommended; do not use capacitor values lower than
100pF to avoid the influence of parasitic capacitances.
Capacitor Selection and
Regulator Stability
For stable operation over the full temperature range and
with load currents up to 100mA, use a 10µF (min) out-
put capacitor with an ESR < 0.5. To reduce noise and
improve load-transient response, stability, and power-
supply rejection, use larger output-capacitor values.
Some ceramic dielectrics exhibit large capacitance and
ESR variation with temperature. For dielectric capacitors
such as Z5U and Y5V, use more capacitance to ensure
stability at low temperatures. With X7R or X5R dielectrics,
10µF should be sufficient at all operating temperatures.
For higher-ESR tantalum capacitors, use larger capaci-
tor values to maintain stability. To improve power-supply
rejection and transient response, use a larger capacitor
than the minimum 0.1µF capacitor between IN and GND.

Ensuring a Valid RESET Output Down to
VIN = 0V (MAX6766/MAX6768/MAX6770/
MAX6772/MAX6774/MAX6774B)
When VIN falls below 1V, RESET current-sinking capa-
bilities decline drastically. High-impedance CMOS-logic
inputs connected to RESET can drift to undetermined
voltages. This presents no problems in most applications,
since most µPs and other circuitry do not operate with
supply voltages below 1V. In applications where RESET
must be valid down to 0V, adding a pulldown resistor
between RESET and ground sinks any stray leakage
currents, holding RESET low (Figure 5). The value of the
pulldown resistor is not critical; 100k is large enough
not to load RESET and small enough to pull RESET to
ground. Open-drain RESET versions are not recommend-
ed for applications requiring valid logic for VIN down to 0V. Figure 5. Ensuring RESET Valid to VIN = 0V
