Overview
The LM4040BIM3X-3.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 3V in a compact SOT-23-3 package. It features an initial accuracy of ±0.2% and a temperature coefficient of 150 ppm/°C. The device supports a maximum cathode current of 15 mA and operates within a temperature range of -40°C to +85°C. Designed for surface-mount installation, it offers high precision for space-constrained applications requiring stable voltage regulation.
Feature Summary
- Micropower shunt architecture designed for low current consumption
- High precision with ±0.2% initial accuracy specification
- Compact SOT-23-3 surface-mount packaging for space efficiency
Applications
- Portable battery-powered instrumentation
- Handheld measurement devices
- Microprocessor system supervisory circuits
- Data acquisition systems
Procurement Notes
Verify the specific suffix (e.g., NOPB) against the official datasheet to confirm RoHS compliance and exact electrical tolerances. Ensure the ordering code matches the required temperature coefficient and accuracy grade. Confirm availability status as distribution channels may vary. Cross-reference the manufacturer's latest documentation for any package or material changes before final procurement.
Selection Notes
Select this component when a fixed 3V reference is required in a small footprint. It is suitable for applications where power consumption must be minimized while maintaining moderate precision. Consider the 15mA current limit for load requirements. Evaluate if the 150 ppm/°C drift meets thermal stability needs compared to lower-drift alternatives.
Part Context
This part belongs to the LM4040 series of micropower shunt voltage references. The 'B' indicates a tighter accuracy grade compared to standard variants. The 'IM3' denotes the SOT-23-3 package type. The 'X' suffix typically indicates tape-and-reel packaging. This series is widely used in industrial and consumer electronics for precise voltage regulation.
Replacement Considerations
LM4040BIM3-3.0/NOPB: Identical electrical specifications but in cut-tape packaging instead of reel.
FAQ
What is the maximum cathode current for this device?
The maximum cathode current is 15 mA.
Does this part support AEC-Q100 automotive qualification?
The provided data does not confirm AEC-Q100 qualification for the LM4040BIM3X-3.0 variant; check the specific datasheet for automotive-grade designations.
