MAX6037_07 Datasheet, PDF (1/18 Pages) Maxim Integrated Products – Low-Power, Fixed and Adjustable Reference with Shutdown in SOT23

19-3192; Rev 1; 12/07
Low-Power, Fixed and Adjustable Reference
with Shutdown in SOT23
General Description
The 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.
