MAX6030BEUR+T

Overview

The MAX6030BEUR+T is a precision series-mode voltage reference delivering a fixed 3.000V output in a compact SOT-23-3 package. It features an initial accuracy of ±0.4% and a maximum temperature coefficient of 30ppm/°C across the -40°C to +85°C range. The device draws a maximum quiescent supply current of 35μA with minimal variation relative to input voltage changes. It supports up to ±500μA load current sourcing and sinking, maintaining stability with capacitive loads up to 2.2nF without requiring external compensation components.

Feature Summary

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision
• Operates with ultra-low quiescent supply current virtually independent of input voltage variations
• Provides stable performance with capacitive loads ranging from 0 to 2.2nF without external compensation
• Features low dropout voltage allowing efficient operation in low-voltage battery-powered systems

Applications

• Hand-Held Equipment
• Data Acquisition Systems
• Industrial and Process-Control Systems
• Battery-Operated Equipment
• Hard-Disk Drives

Procurement Notes

Verify the specific suffix 'B' indicates the ±0.4% accuracy grade rather than the tighter ±0.2% 'A' grade. Confirm the '+T' designation corresponds to tape-and-reel packaging if automated assembly is required. Ensure the operating environment remains within the specified -40°C to +85°C temperature range to maintain guaranteed electrical characteristics.

Selection Notes

Select this component when a fixed 3V reference is required with moderate precision in space-constrained designs. It is suitable for applications where power efficiency is critical due to its micropower consumption. Consider the ±0.4% tolerance against system error budgets. Verify that the input voltage stays above the minimum dropout requirement to ensure regulation.

Part Context

This part belongs to the MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/MAX6045/MAX6050 family of precision, low-dropout, micropower voltage references. All members share the same SOT-23-3 footprint and core architecture but offer different fixed output voltages ranging from 1.247V to 5.000V. The family is designed for battery-operated, low-voltage systems requiring high accuracy.

Replacement Considerations

MAX6030AEUR+T offers tighter initial accuracy (±0.2%) and lower temperature drift (max 20ppm/°C) in the same package.
