MAX6030BEUR-T

Overview

The MAX6030BEUR-T is a precision series-mode voltage reference delivering a fixed 3.000V output in a miniature SOT23-3 surface-mount 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, which varies by only 0.8μA/V with input voltage changes. It supports sourcing and sinking up to 500μA of load current with a dropout voltage of 200mV at full load. Input voltage ranges from VOUT+0.2V to 12.6V.

Feature Summary

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision.
• Operates with ultra-low quiescent supply current that remains virtually independent of the supply voltage.
• Internally compensated design eliminates the need for external compensation capacitors.
• Capable of both sourcing and sinking load currents while maintaining stability with capacitive loads up to 2.2nF.

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 'B' grade designation corresponds to the required ±0.4% initial accuracy specification. Ensure the input voltage source can provide sufficient current during turn-on transients to guarantee reliable startup within the specified operating temperature range.

Selection Notes

Select this component when a fixed 3V reference is required in space-constrained designs utilizing SOT23-3 packages. It is suitable for low-voltage battery-powered systems due to its minimal dropout voltage and supply-independent current consumption. Consider the ±0.4% accuracy grade if tighter tolerances are not necessary for the application's signal chain requirements.

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 identical pinouts, package styles, and core architectural features, differing primarily in their fixed output voltage levels and specific accuracy grades.

Replacement Considerations

Direct functional replacements within the same family include MAX6030AEUR-T (±0.2% accuracy) or MAX6030BEUR+T (lead-free RoHS compliant). Verify that any substitute maintains the SOT23-3 footprint and matches the 3.000V output requirement.
