Low-Power, Fixed and Adjustable Reference with Shutdown in SOT23
General DescriptionThe MAX6037 family of low-dropout, micropower volt-
age references offer fixed and adjustable output volt-
age options ranging from 1.184V to 5V. Connect an
external resistive-divider on the MAX6037_ADJ to
adjust the output voltage from 1.184V to 5V. The other
devices in the MAX6037 family feature fixed output volt-
ages of 1.25V, 2.048V, 2.5V, 3.0V, 3.3V, and 4.096V.
The MAX6037 offers shutdown functionality with an
active-low shutdown (500nA, max).
These series-mode voltage references operate from a
2.5V to 5.5V supply and consume 275µA (max) quies-
cent current. The output is stable driving loads from
0.02µF to 1µF and can source and sink 5mA of load
current. The MAX6037 offers a low temperature coeffi-
cient of 25ppm/°C and initial accuracy of ±0.2% (max).
The low dropout voltage (100mV, max at 1mA) and
supply-independent, low supply current make the
MAX6037 ideal for battery-powered applications.
The MAX6037 is available in the miniature 5-pin SOT23
package and is specified over the -40°C to +125°C
automotive temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
