MAX6037AAUK30+T

Overview

The MAX6037AAUK30+T is a low-dropout, micropower voltage reference from Analog Devices/Maxim Integrated. It provides a fixed output voltage of 3.0V with an initial accuracy of ±0.2% and a maximum temperature coefficient of 25ppm/°C. The device operates within a supply voltage range of 2.5V to 5.5V and features active-low shutdown functionality that reduces quiescent current to less than 500nA. It is housed in a 5-pin SOT-23 package and is specified over the automotive temperature range of -40°C to +125°C.

Feature Summary

• Active-low shutdown mode reduces quiescent current to below 500nA for power conservation
• Low dropout voltage capability allows operation in low-voltage battery-powered applications
• High precision A-grade performance with ±0.2% initial accuracy and 25ppm/°C temperature coefficient
• Capable of sourcing and sinking up to 5mA of load current

Applications

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

Procurement Notes

Verify the specific suffix 'UK30' corresponds to the 3.0V fixed output variant when ordering. Confirm the 'A' grade designation ensures the required ±0.2% accuracy and 25ppm/°C temperature coefficient specifications are met for the application. Ensure the '+T' tape and reel packaging format aligns with automated assembly requirements.

Selection Notes

Select this component when a stable 3.0V reference is required in space-constrained designs utilizing the SOT-23-5 package. It is suitable for systems demanding high precision (±0.2%) and low temperature drift (25ppm/°C). Consider the shutdown feature if power management during idle states is critical for battery life extension.

Part Context

This part belongs to the MAX6037 family of low-power voltage references. The family includes fixed output options ranging from 1.25V to 4.096V, as well as an adjustable version. The 'A' grade denotes tighter accuracy and temperature stability compared to B and C grades. All variants share the same pinout and general electrical characteristics, differing primarily in output voltage and precision levels.

Replacement Considerations

Other members of the MAX6037 family, such as MAX6037BAUK30+T or MAX6037CAUK30+T, offer the same 3.0V output but with lower accuracy grades (±0.3% and ±0.5%, respectively). These may serve as functional substitutes if the strict ±0.2% accuracy and 25ppm/°C tempco of the AA grade are not required.
