LM4040D30H5TA

Overview

The LM4040D30H5TA is a precision micropower shunt voltage reference from Diodes Incorporated, providing a fixed 3.0V output with ±1% initial tolerance at +25°C. It operates within an extended temperature range of -40°C to +125°C and features a maximum temperature coefficient of 100 ppm/°C. The device supports a wide operating current range from 60µA to 15mA and exhibits low output noise of 45µVRMS (10Hz to 10kHz). It utilizes the SC70-5 package, which is currently designated as End of Life.

Feature Summary

• Provides stable 3.0V reference voltage with high precision over industrial temperatures
• Operates efficiently across a wide current range suitable for power-constrained designs
• Maintains stability without requiring external output capacitors
• Features low noise characteristics for sensitive signal processing applications

Applications

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

Procurement Notes

Verify component status before procurement as the SC70-5 package variant is officially listed as End of Life by the manufacturer. Confirm availability through authorized distributors or consider alternative packages such as SOT23 for new designs. Ensure compliance with RoHS and lead-free requirements specified in the datasheet.

Selection Notes

Select this component when a fixed 3.0V reference with 1% accuracy is required in space-constrained environments utilizing the SC70-5 footprint. Evaluate thermal management needs given the package's thermal resistance. Consider the SOT23 version if long-term supply continuity is critical due to the EOL status of the H5 package.

Part Context

This part belongs to the LM4040 family of bandgap circuits designed for precision micro-power voltage referencing. The D-grade designation indicates a 1% initial tolerance, distinguishing it from higher precision B and C grades. The H5 suffix identifies the specific SC70-5 surface mount package configuration.

Replacement Considerations

LM4040D30FTA is the direct pin-compatible alternative available in the SOT23 package.
