MAX6037CAUK12-T

Overview

The MAX6037CAUK12-T 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 ±0.2% (max) and a temperature coefficient of 25ppm/°C (max). The device operates from a 2.5V to 5.5V supply and consumes 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 5mA of load current and remains stable driving loads from 0.02µF to 1µF. The component is housed in a 5-pin SOT-23 package and is specified over the -40°C to +125°C automotive temperature range.

Feature Summary

• Includes shutdown functionality with active-low control for ultra-low standby current consumption.
• Features low dropout voltage of 100mV (max) at 1mA load current for efficient battery operation.
• Capable of sourcing and sinking 5mA of load current while maintaining stability.

Applications

• Medical Equipment
• Portable Equipment
• Wireless LAN
• Precision Regulators

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 'A' grade specifications regarding the ±0.2% initial accuracy and 25ppm/°C temperature coefficient if these performance levels are critical for the design. Ensure the input voltage range of 2.5V to 5.5V aligns with the system power supply constraints.

Selection Notes

Select this component for applications requiring high precision and low power consumption in a small footprint. The fixed 1.25V output is suitable for reference inputs in data converters or sensor biasing. Consider the automotive temperature range (-40°C to +125°C) for rugged environments. The shutdown feature makes it ideal for battery-powered devices where standby current must be minimized.
