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 surface-mount package. It features an initial accuracy of ±0.2% and a maximum temperature coefficient of 15ppm/°C across the 0°C to +70°C range, extending to 20ppm/°C over the full -40°C to +85°C operating temperature range. The device draws a maximum quiescent supply current of 35μA with minimal variation relative to input voltage changes. It supports sourcing and sinking up to 500μA of load current while maintaining stability with capacitive loads ranging from 0 to 2.2nF without requiring external compensation components.

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 provides supply current virtually independent of input voltage.
• Internally compensated design remains stable with capacitive loads up to 2.2nF, removing the requirement for external compensation capacitors.

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 EUR package code corresponds to the SOT-23-3 footprint required by the PCB layout. Check for RoHS compliance status indicated by the '+' suffix in the final part number.

Selection Notes

Select this component when a fixed 5V reference is required in space-constrained designs. The series-mode topology offers superior efficiency compared to shunt references by drawing current only as needed by the load. Verify that the input voltage exceeds the minimum dropout requirement of VOUT plus 0.2V. Consider the 500μA source/sink capability against the application's dynamic load requirements.

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, packages, and core architectural features, differing primarily in their fixed output voltage levels. The MAX6050 specifically provides the highest voltage output within this standard lineup.

FAQ

Does the MAX6050AEUR+T 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 recommended if the load or supply experiences step changes to improve transient response.

What is the maximum output short-circuit current?

The output short-circuit current is limited to 4mA whether shorted to ground or to the input voltage.
