The MAX6037 family is a low-dropout, micropower voltage reference that offers 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.
The MAX6037 family provides low‑dropout, micropower voltage references with both fixed and adjustable output options ranging from 1.184 V to 5 V. It operates from a 2.5 V to 5.5 V supply and includes an active‑low shutdown mode that reduces quiescent current to less than 500 nA.
Key features include a low temperature coefficient of 25 ppm/°C, a typical dropout voltage of 100 mV at 1 mA load, and the ability to source or sink up to 5 mA. The device is supplied in a 5‑pin SOT‑23 package and is specified for automotive temperature ranges (‑40 °C to +125 °C).
