Automotive Micropower Linear Regulators  
with Supervisor  
General Description  
Features  
♦ Low 31µA Quiescent Current  
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.  
♦ 4V to 72V Wide Input Voltage Range  
♦ 100mA Output Current Capability  
♦ Dropout Voltage of 620mV with 5V Output  
at 100mA  
♦ Fixed Output-Voltage Options: 5V, 3.3V, 2.5V,  
and 1.8V  
♦ Adjustable Output Voltages from 1.8V to 11V  
♦ Open-Drain or Push-Pull RESET Output  
♦ Fixed or Capacitor-Adjustable Reset Timeouts  
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.  
♦ Small, Thermally Enhanced 1.9W, 3mm x 3mm  
TDFN Package  
♦ Overtemperature and Short-Circuit Protection  
♦ Fully Specified from -40°C to +125°C  
Ordering Information  
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 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.  
+Denotes lead-free package.  
*EP = Exposed paddle.  
For tape-and-reel orders add a “T” after the “+” symbol to com-  
plete the part number. Tape-and-reel orders are available in  
2.5k increments. Nonstandard versions require a 10k minimum  
order quantity.  
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.
