LM4040B50H5TA

Overview

The LM4040B50H5TA is a precision micropower shunt voltage reference manufactured by Diodes Incorporated. It provides a fixed output voltage of 5.0 V with an initial tolerance of ±0.2% at +25°C. The device operates within an extended temperature range from -40°C to +125°C and features a maximum average temperature coefficient of 100 ppm/°C. It utilizes the SC70-5 surface mount package, which has been designated as End of Life (EOL). The component supports a wide operating current range from 60µA to 15mA.

Feature Summary

• Provides stable 5.0 V reference voltage with high initial accuracy
• Operates reliably across extended industrial temperature ranges
• Designed for space-constrained applications using compact packaging
• Maintains stability under varying load conditions without external capacitors

Applications

• Battery powered equipment
• Precision power supplies
• Portable instrumentation
• Data acquisition systems

Procurement Notes

Verify that the SC70-5 package variant is acceptable for the design, as this specific package code is officially listed as End of Life. Confirm that the standard SOT23 package serves as the intended active replacement. Ensure compliance with RoHS and Halogen-free requirements before finalizing procurement plans.

Selection Notes

Select this component when a 5.0 V reference with ±0.2% accuracy is required in a small footprint. Note that the SC70-5 package is obsolete; the SOT23 package is the recommended alternative for new designs. Verify thermal management capabilities if operating near maximum junction temperatures.

Part Context

This part belongs to the LM4040 family of bandgap circuits designed for precision micro-power voltage referencing. The family includes various voltage options and accuracy grades. The H5 suffix specifically denotes the SC70-5 package, which is distinct from the currently supported SOT23 variants.
