MAX6063BEUR

Overview

The MAX6063BEUR+T is a precision, low-dropout, micropower series voltage reference from Analog Devices. It delivers a fixed 3V output with an initial accuracy of ±0.4% and a maximum temperature coefficient of 30ppm/°C for the B grade. The device operates within an input voltage range up to 12.6V or 13.5V and provides a maximum output current of 5mA. It is housed in a compact SOT-23-3 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Provides stable 3V reference output with high initial accuracy
• Low dropout operation suitable for battery-powered applications
• Micropower consumption design for energy efficiency
• Compact SOT-23-3 surface-mount packaging

Applications

• Portable instrumentation requiring precise voltage references
• Battery-operated measurement systems
• Data acquisition channels needing stable reference voltages
• Medical devices with strict power constraints

Procurement Notes

Verify the specific suffix (+T) indicates tape-and-reel packaging when ordering. Confirm the B-grade designation corresponds to the required 30ppm/°C temperature coefficient. Ensure the SOT-23-3 footprint matches your PCB layout. Check for RoHS compliance status if required by your manufacturing standards. Validate input voltage limits against your system supply rails.

Selection Notes

Select this component when a fixed 3V reference is needed with tight tolerance requirements. The B-grade variant offers superior temperature stability compared to standard grades. Consider the 5mA output current capability for driving ADCs or comparators directly. The low dropout characteristic allows operation from supplies close to the output voltage. Evaluate power dissipation based on the difference between input and output voltages.

Part Context

This part belongs to the MAX606x series of precision voltage references designed for low-power applications. It complements other variants like the MAX6065 (5V) and MAX6064 (2.5V) within the same family. The series is characterized by its micropower operation and high accuracy, making it suitable for portable electronics. Analog Devices acquired Maxim Integrated, under which this product line was originally developed.

Replacement Considerations

The MAX6063BEUR-T is listed as an alternative part number for the same device. Verify pin compatibility and electrical specifications before substitution. Other series references may require circuit adjustments due to different output currents or temperature coefficients.
