Overview
The LM4040BIM3X-5.0/NOPB is a micropower shunt voltage reference from Texas Instruments, offering a fixed 5V output with ±0.2% initial accuracy and a temperature coefficient of 100 ppm/°C. Housed in a compact SOT-23 package, it operates within a -40°C to +85°C range and supports a maximum cathode current of 15mA. Designed for space-constrained applications, this device provides stable reference performance with low power consumption.
Feature Summary
- Micropower shunt architecture designed for minimal current drain
- High precision with ±0.2% initial accuracy for stable reference
- Compact SOT-23 surface-mount packaging for space efficiency
Applications
- Portable battery-powered instrumentation
- Handheld measurement devices
- Data acquisition systems requiring stable references
Procurement Notes
Verify the complete part number including suffixes such as NOPB and X to ensure correct packaging and lead-free compliance. Confirm that the specific accuracy grade matches design requirements, as variations exist within the LM4040 family. Cross-reference datasheet specifications against application constraints before finalizing procurement decisions.
Selection Notes
Select this component when high precision and low power are critical in a small footprint. The SOT-23 form factor suits dense PCB layouts. Ensure the shunt topology aligns with circuit design, as it requires a minimum operating current to maintain regulation. Compare temperature coefficients if wider thermal ranges are needed.
Part Context
This device belongs to the LM4040 series of micropower shunt voltage references. It shares architectural similarities with other members like the LM4040DIM3X variants but differs in accuracy grades and specific output voltages. The series is widely used in industrial and consumer electronics where reliable voltage referencing is essential.
Replacement Considerations
LM4040BIM3-5.0/NOPB is a non-x variant of the same electrical specification. LM4040B50IDBZR offers similar 5V performance in an alternative package. Verify pinout compatibility and thermal characteristics when substituting.
