MAX6141EUR

Overview

The MAX6141EUR is a low-dropout, micropower three-terminal voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides fixed output voltages of 2.5V, 4.096V, 4.5V, or 5.0V. The device features a typical temperature coefficient of 15ppm/°C and a maximum of 50ppm/°C. It operates with a supply current of 75µA, which remains independent of input voltage variations. The component offers a low dropout voltage of 200mV, making it suitable for 3V and 5V systems. It is housed in a compact 3-pin SOT-23 package.

Feature Summary

• Low dropout voltage of 200mV enables efficient operation in 3V and 5V systems
• Micropower consumption with 75µA supply current independent of input voltage
• Stable performance across all capacitive loads up to 10nF

Applications

• Battery-powered systems
• Portable and hand-held equipment
• Data-acquisition systems
• Instrumentation and process control

Procurement Notes

Verify the specific output voltage variant (2.5V, 4.096V, 4.5V, or 5.0V) required for the design, as the base part number covers multiple options. Confirm the package type matches the PCB footprint, specifically the 3-pin SOT-23 configuration. Ensure compatibility with the system's input voltage range given the 200mV dropout characteristic. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when low power consumption is critical for battery life, as the supply current does not vary significantly with input voltage changes. The low dropout voltage makes it preferable over standard references in systems where the input voltage is close to the desired reference level. Consider the 15ppm/°C typical temperature coefficient for applications requiring moderate precision without the cost of higher-grade references.

Part Context

This component belongs to the MAX61xx family of low-dropout, micropower voltage references from Maxim Integrated. The family includes variants like MAX6125, MAX6145, MAX6150, and MAX6160, offering different fixed or adjustable output voltages. While other members may use different packages such as SOT143, the MAX6141EUR specifically utilizes the 3-pin SOT-23 form factor for space-constrained designs.

Replacement Considerations

Direct substitutes within the same family include MAX6125, MAX6145, MAX6150, and MAX6160, provided the output voltage requirements align. Verify that alternative parts maintain the 3-pin SOT-23 package and similar electrical characteristics, particularly the 75µA supply current and 200mV dropout voltage.
