LM4040D50H5TA

Overview

The LM4040D50H5TA is a precision micropower shunt voltage reference manufactured by Diodes Incorporated, featuring a fixed output voltage of 5.0V with an initial tolerance of ±1%. It utilizes the SC70-5 package and operates within an extended temperature range of -40°C to +125°C. The device maintains excellent performance across a wide operating current range from 60µA to 15mA, with a typical temperature coefficient of 30ppm/°C at 10mA reverse current. It exhibits low output noise of 80µVRMS in the 10Hz to 10kHz bandwidth and demonstrates high stability when used with capacitive loads.

Feature Summary

• Provides stable 5.0V reference with ±1% initial accuracy
• Operates reliably across extended industrial temperature ranges
• Maintains stability under varying capacitive load conditions
• Delivers low noise performance for precision applications

Applications

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

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific ordering suffix corresponds to the SC70-5 package variant. Ensure compliance with RoHS directives and halogen-free requirements as specified in the manufacturer documentation. Validate part markings against official identification codes prior to integration.

Selection Notes

Select this component for designs requiring a compact surface-mount voltage reference with moderate precision. Consider the SC70-5 package dimensions for space-constrained layouts. Evaluate the minimum operating current requirements against the system's quiescent current capabilities. Verify thermal management needs based on the maximum shunt current limits.

Part Context

This device belongs to the LM4040 family of bandgap circuits designed for precision micro-power voltage referencing. The family includes various grades offering different initial tolerances and multiple fixed output voltage options. The H5 suffix specifically denotes the SC70-5 package configuration, which provides a small outline form factor suitable for dense PCB layouts.

Replacement Considerations

SC70-5 variants are designated as End of Life (EOL). Designers should transition to SOT23 package alternatives such as the LM4040D50FTA for continued production support. Verify pin compatibility and electrical specifications before substituting with other manufacturers' equivalents.
