ZXRE4041ER

Overview

The ZXRE4041ER is a micropower voltage reference IC manufactured by Diodes Incorporated, housed in an SOT-23 surface-mount package. It provides a precise 1.225V output with a typical temperature coefficient of 20ppm/°C and operates within a current range of 30µA to 12mA. The device maintains stability under capacitive loads and offers tolerance grades of 0.5%, 1%, and 2%.

Feature Summary

• Micropower bandgap circuit designed for precision voltage referencing
• Unconditionally stable operation with high capacitive load tolerance
• Small outline SOT-23 package suitable for space-constrained designs

Applications

• Battery powered equipment
• Precision power supplies
• Portable instrumentation
• Data acquisition systems
• A/D and D/A converters

Procurement Notes

Verify the specific suffix (e.g., CF, DF) against the datasheet ordering table to confirm the exact initial accuracy grade required. Confirm that the E-Line variants are obsolete and ensure the selected part utilizes the standard SOT-23 package configuration.

Selection Notes

Select this component when a low-profile SOT-23 footprint is necessary alongside a fixed 1.225V reference. Consider the 30µA minimum operating current for battery applications and verify that the 20ppm/°C typical temperature coefficient meets the system's thermal stability requirements.
