MAX6037CAUK12

Overview

The MAX6037CAUK12 is a low-dropout, micropower voltage reference from the MAX6037 family. It provides a fixed output voltage of 1.25V with an initial accuracy of ±0.5% and a temperature coefficient of 6ppm/°C. The device operates from a 2.5V to 5.5V supply, consuming a maximum quiescent current of 275µA. It features shutdown functionality with active-low control, drawing less than 500nA in shutdown mode. The output can source and sink up to 5mA of load current while maintaining stability with loads between 0.02µF and 1µF. It is housed in a 5-pin SOT-23 package and specified over the -40°C to +125°C automotive temperature range.
