REF5020MDREP

Overview

The REF5020MDREP is a precision series voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 4.096 V with an initial accuracy of ±0.05%. The device operates within an input voltage range of 4.296 V to 18 V and delivers a maximum output current of 10 mA. Key electrical specifications include a temperature coefficient of 5 ppm/°C, a supply current of 1.25 mA, and low noise performance of 12 µVpp from 0.1 Hz to 10 Hz. It functions reliably across a junction temperature range of -55°C to +125°C.

Feature Summary

• Delivers high-precision voltage regulation with ±0.05% initial accuracy for critical measurement applications.
• Features very low drift characteristics with a temperature coefficient of 5 ppm/°C over the extended industrial temperature range.
• Provides low-noise performance suitable for sensitive analog signal processing and data conversion circuits.

Applications

• High-resolution data acquisition systems requiring stable reference voltages
• Precision instrumentation and test equipment calibration
• Medical imaging devices such as ECG and ultrasound systems

Procurement Notes

Verify the specific suffix MDREP corresponds to the 8-SOIC package and enhanced-product status when ordering. Confirm that the required operating temperature range extends to -55°C, as standard commercial variants may differ. Ensure input voltage exceeds the minimum dropout requirement of 4.296 V for proper regulation. Check for moisture sensitivity level (MSL) requirements during storage and handling procedures.

Selection Notes

Select this component when a fixed 4.096 V output is required with tight tolerance and low temperature drift. Compare against REF50xx family members if different output voltages or package types are needed. Consider the 10 mA load capability and 1.25 mA quiescent current for power budgeting. Verify compatibility with 8-SOIC footprint constraints in the design layout.

Part Context

This part belongs to the REF50xx enhanced-product series from Texas Instruments, designed for demanding environments. It shares architectural similarities with other REF50xx devices but offers specific performance metrics tailored for high-reliability applications. The series is widely used in industries requiring strict adherence to precision and stability standards.

Replacement Considerations

REF5020IDR is a commercial-grade alternative with similar electrical specifications but a limited operating temperature range of -40°C to +125°C. REF5020I is another variant offering comparable performance. Verify package compatibility and thermal requirements before substitution.
