MAX6050AEUR-T

Overview

The MAX6050AEUR-T is a precision series-mode voltage reference delivering a fixed 5.000V output in a compact SOT-23-3 package. It operates within an input voltage range of 5.2V to 12.6V, drawing a maximum quiescent supply current of 35μA with minimal variation relative to the input voltage. The device provides ±500μA of source and sink current capability while maintaining an initial accuracy better than 0.2% and a temperature coefficient under 20ppm/°C across the -40°C to +85°C extended operating range.

Feature Summary

• Proprietary curvature-correction circuit combined with laser-trimmed thin-film resistors ensures high precision and low temperature drift.
• Series-mode architecture eliminates the need for external biasing resistors and maintains efficiency independent of supply voltage changes.
• Internally compensated design guarantees stability with capacitive loads up to 2.2nF without requiring external compensation components.

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 sourcing. Confirm that the '+A' designation corresponds to the required 0.2% initial accuracy grade. Ensure the ordering code matches the exact manufacturer part number to guarantee compatibility with the specified electrical characteristics and RoHS compliance status.

Selection Notes

Select this component when a stable 5V reference is required in space-constrained designs utilizing the SOT-23-3 footprint. It is suitable for applications demanding low power consumption where supply current must remain nearly constant despite input voltage fluctuations. Consider the dropout voltage requirements to ensure the minimum input voltage supports the necessary load current conditions.

Part Context

This device belongs to the MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/MAX6045/MAX6050 family of precision, low-power, low-dropout voltage references. All members share identical pinouts, package styles, and core architectural features, differing primarily in their fixed output voltage levels ranging from 1.247V to 5.000V.

Replacement Considerations

Direct functional substitutes within the same family include MAX6045AEUR+T (4.5V) if voltage tolerance permits. Other compatible options are MAX6030AEUR+T (3.0V), MAX6025AEUR+T (2.5V), MAX6021AEUR+T (2.048V), and MAX6012AEUR+T (1.247V). Verify that the alternative output voltage aligns with system requirements before substitution.

FAQ

Does the MAX6050 require an external capacitor for stability?

No, the device is internally compensated and stable with capacitive loads ranging from 0 to 2.2nF. An external capacitor is optional but can improve transient response in systems with significant load or supply step changes.

How does the supply current behave with respect to input voltage?

The quiescent supply current is virtually independent of the supply voltage, exhibiting only a 0.8μA/V variation across the operating input range. This contrasts with shunt references that waste current through series resistors.
