MAX6037CAUK30+T

Overview

The MAX6037CAUK30+T is a low-dropout, micropower voltage reference from the MAX6037 family. It provides a fixed output voltage of 3.0V with an initial accuracy of ±0.5% and a maximum temperature coefficient of 50ppm/°C. The device operates from a supply voltage range of 2.5V to 5.5V, consuming a typical quiescent current of 210µA. It features active-low shutdown functionality that reduces supply current to less than 500nA. The component supports sourcing and sinking up to 5mA of load current and maintains stability with capacitive loads between 0.02µF and 1µF. 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 less than 500nA for power conservation
• Low dropout voltage capability allows operation in low-voltage applications
• Capable of sourcing and sinking up to 5mA of load current
• Stable driving capacitive loads ranging from 0.02µF to 1µF

Applications

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

Procurement Notes

Verify the specific suffix 'C' indicates the 0.5% initial accuracy grade and 'K30' denotes the 3.0V fixed output. Confirm the '+T' suffix corresponds to tape-and-reel packaging. Ensure the component matches the manufacturer's lead-free specifications and check for any regional distribution restrictions or obsolescence notices prior to finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.0V reference with moderate precision (±0.5%) is required. It is suitable for battery-powered designs due to its low quiescent current and shutdown feature. Consider the 50ppm/°C temperature coefficient against stricter requirements; if higher precision is needed, evaluate the 'A' grade variant with ±0.2% accuracy and 25ppm/°C tempco instead.

Part Context

This part belongs to the MAX6037 family of low-power voltage references manufactured by Analog Devices / Maxim Integrated. The family includes fixed output options such as 1.25V, 2.048V, 2.5V, 3.0V, 3.3V, and 4.096V, as well as an adjustable version. The CAUK30 designation specifically identifies the C-grade accuracy and 3.0V output within the SOT-23-5 package form factor.
