MAX6037A, MAX6037B, MAX6037C:Low-Power, Fixed and Adjustable Reference with Shutdown in SOT23

Industry's Lowest Drift, Adjustable-Output Voltage Reference

The MAX6037 family of low-dropout, micropower voltage references offer fixed and adjustable output voltage 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 voltages 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) quiescent 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 coefficient 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.
