Overview
The LM4040BIM7-5.0/NOPB is a fixed shunt voltage reference from Texas Instruments, providing a nominal output of 5V with an initial accuracy of ±0.2%. Housed in a compact SC-70-5 (SOT-353) surface-mount package, it operates within a temperature range of -40°C to +125°C and features a temperature coefficient of 50 ppm/°C. The device supports a maximum cathode current of 90 µA and delivers up to 15 mA load current, ensuring stable performance for precision analog circuits.
Feature Summary
- High precision with ±0.2% initial accuracy
- Low temperature drift at 50 ppm/°C
- Compact SC-70-5 surface-mount packaging
Applications
- Precision data acquisition systems
- Portable instrumentation
- Battery-powered measurement devices
Procurement Notes
Verify the specific suffix 'M7' against official documentation to confirm the SC-70-5 package type, as variations exist within the LM4040 family. Ensure the component meets AEC-Q100 automotive qualification requirements if intended for automotive applications. Cross-reference the exact part number with manufacturer datasheets to validate pinout compatibility and thermal characteristics before integration.
Selection Notes
Select this component when high accuracy and low temperature drift are critical in space-constrained designs. The SC-70-5 package offers a smaller footprint compared to traditional SOT-23 options. Consider the 50 ppm/°C temperature coefficient for applications requiring stability across wide industrial temperature ranges, particularly where power consumption must remain low due to the micropower design.
Part Context
This device belongs to the LM4040 series of micropower shunt voltage references. It serves as a high-precision alternative to standard Zener diodes, offering superior regulation and lower noise. The series is designed for applications requiring stable reference voltages in minimal board space, supporting both industrial and automotive environments through its robust operating temperature range and reliability standards.
Replacement Considerations
The TL4050C50QDCKT is listed as a discontinued substitute. Verify electrical parameter alignment, specifically the 50 ppm/°C temperature coefficient and ±0.5% accuracy, before considering alternatives.
