MAX6030AEUR+T

Overview

The MAX6030AEUR+T is a precision, low-power, low-dropout series-mode voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 3.000V with an initial accuracy of ±0.2%. The device operates over an extended temperature range from -40°C to +85°C and features a maximum temperature coefficient of 20ppm/°C across this range. It draws a quiescent supply current of 27μA (max 35μA) and can source or sink up to 500μA of load current. The input voltage range extends from VOUT + 0.2V to 12.6V.

Feature Summary

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision
• Series-mode architecture eliminates the need for external biasing resistors required by shunt references
• Internally compensated design ensures stability without requiring external compensation capacitors
• Supply current remains virtually independent of input voltage variations

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 '+A' grade designation matches the required ±0.2% initial accuracy specification. Ensure the SOT-23-3 package footprint aligns with the target PCB layout. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a fixed 3V reference is needed in space-constrained designs. It is suitable for battery-powered applications due to its ultra-low quiescent current and independence from supply voltage changes. Consider the 200mV dropout voltage at full load when determining minimum input requirements. Verify that the 500μA output capability meets the downstream circuit's current demands.

Part Context

This part belongs to the MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/MAX6045/MAX6050 family of precision voltage references. All members share identical pinouts, packages, and core technologies, differing only in their fixed output voltages. The MAX6030 specifically targets applications requiring a 3V reference level within this miniature surface-mount form factor.

Replacement Considerations

MAX6030BEUR+T offers the same package and function but with ±0.4% initial accuracy.
