ADR5043BRTZ-REEL7

Overview

The ADR5043BRTZ-REEL7 is a precision micropower shunt voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 3.0 V with an initial accuracy of ±0.1% and a maximum temperature coefficient of 75 ppm/°C. The device operates within a wide current range from 50 µA to 15 mA and functions reliably across an extended temperature range of −40°C to +125°C. Housed in an ultracompact SOT-23 package, it requires no external compensation capacitor for stability.

Feature Summary

• Ultracompact packaging suitable for space-critical applications
• High initial accuracy with low temperature drift characteristics
• Capable of operation without external capacitors while maintaining stability

Applications

• Portable battery-powered equipment
• Automotive systems
• Data acquisition systems
• Instrumentation and process control
• Energy management

Procurement Notes

Verify the specific suffix BRTZ corresponds to the SOT-23-3 package configuration and REEL7 indicates reel packaging when sourcing. Confirm RoHS compliance status as indicated by the Z suffix. Ensure the ordering quantity matches the manufacturer's standard reel size requirements for this specific part number variant.

Selection Notes

Select this component for designs requiring a stable 3.0 V reference in minimal footprint environments. The wide operating current range supports both low-power standby modes and higher drive requirements. Verify that the thermal resistance characteristics of the SOT-23 package align with the expected power dissipation in the target application environment.
