LM4040B30H5TA

Overview

The LM4040B30H5TA is a precision micro-power shunt voltage reference providing a nominal output of 3.0V with an initial tolerance of ±0.2% at +25°C. It operates within a reverse current range of 60µA to 15mA and features a typical temperature coefficient of 20ppm/°C. The device utilizes an SC70-5 package, which is designated as End of Life (EOL). It supports an extended operating ambient temperature range from -40°C to +125°C and exhibits low output noise of 45µVRMS in the 10Hz to 10kHz bandwidth.

Feature Summary

• Provides high-precision voltage referencing with tight initial tolerance specifications for accurate circuit regulation.
• Operates efficiently across a wide dynamic current range suitable for battery-powered and space-constrained designs.
• Maintains stability under capacitive loads without requiring external output capacitors.

Applications

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

Procurement Notes

Verify component status carefully as the SC70-5 package variant is officially listed as End of Life by Diodes Incorporated. Confirm availability through authorized distributors or secondary markets if sourcing for new production. Ensure compatibility with existing PCB footprints designed for the obsolete package style before procurement decisions are finalized.

Selection Notes

Select this specific grade for applications demanding the highest initial accuracy among the available options. Consider the EOL status when planning long-term product lifecycles. Evaluate thermal management requirements given the small package size and power dissipation limits. Verify that the 3.0V reference level aligns precisely with system voltage requirements.

Part Context

This component belongs to the LM4040 family of bandgap voltage references manufactured by Diodes Incorporated. The family includes various voltage outputs and tolerance grades packaged in SOT23 and SC70-5 formats. The H5 suffix specifically denotes the SC70-5 package configuration, which offers a compact footprint compared to standard SOT23 variants.

Replacement Considerations

Consider LM4040B30FTA as a direct functional substitute in the SOT23 package. Verify pinout compatibility and physical footprint differences during transition. Review updated datasheets for any minor parameter shifts between package types.
