MAX6010AEUR+T

Overview

The MAX6010AEUR+T is a precision, micropower, 3V series voltage reference in a SOT23-3 package. It operates with an input voltage range of 3.2V to 5.5V and delivers a fixed 3V output. The device features an initial accuracy of ±0.2% and a maximum temperature coefficient of 50ppm/°C. Quiescent supply current is limited to 5µA (max), varying by only 0.05µA/V across the input range. It supports sourcing up to 7mA and sinking up to 1mA, with a dropout voltage of 200mV (max). Stability is maintained with capacitive loads between 1nF and 1µF.

Feature Summary

• Ultra-low quiescent supply current of 5µA maximizes battery life in portable applications
• Low-dropout design enables operation from inputs as low as 3.2V while maintaining regulation
• High initial accuracy of ±0.2% ensures precise reference performance without external trimming
• Compact three-terminal SOT23 package minimizes board space requirements

Applications

• Battery-operated equipment
• Portable electronic devices
• Lens image stabilization systems
• Data-acquisition systems
• Industrial and process-control systems

Procurement Notes

Verify the specific grade suffix 'A' corresponds to the required ±0.2% initial accuracy and 50ppm/°C temperature drift specifications. Confirm the '+T' designation indicates tape-and-reel packaging for automated assembly. Ensure the operating environment remains within the -40°C to +85°C temperature range to maintain guaranteed electrical characteristics. Validate that the application circuit includes appropriate input and output capacitance to ensure stability.

Selection Notes

Select this component when a fixed 3V reference is required with minimal power consumption. The low dropout voltage allows efficient operation from single-cell or dual-cell battery sources. The ±0.2% accuracy eliminates the need for calibration in many precision applications. Consider the 5µA supply current against total system budget constraints. Verify load requirements do not exceed the 7mA sourcing capability.

Part Context

The MAX6010 series comprises precision, low-noise, low-dropout voltage references designed for battery-powered systems. The AEUR+T variant specifically denotes the A-grade version with ±0.2% accuracy, housed in a SOT23-3 surface-mount package. This family offers alternatives with different accuracies and output voltages, but the MAX6010AEUR+T is optimized for applications demanding high precision and ultra-low power consumption in a compact form factor.
