Overview
The LM4040DIM3X-5.0/NOPB is a fixed shunt voltage reference from the LM4040 series, manufactured by Texas Instruments. It provides a nominal output voltage of 5 V with an initial accuracy of ±1%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 150 ppm/°C. Designed for surface-mount applications, it utilizes a SOT-23 package. The component supports a maximum shunt current of 15 mA and draws a typical cathode current of 70 µA.
Feature Summary
- Provides stable fixed voltage reference in compact SOT-23 surface-mount package
- Operates as a shunt regulator with low quiescent current consumption
- Maintains specified performance across industrial temperature range
Applications
- Precision analog-to-digital converter (ADC) reference inputs
- Data acquisition systems requiring stable voltage sources
- Battery-powered instrumentation circuits
Procurement Notes
Verify the specific suffix DIM3X against the official datasheet to confirm pinout and marking compatibility. Ensure the required accuracy class matches the ±1% tolerance documented for this variant. Confirm RoHS compliance status through the manufacturer's latest documentation before integration into production designs.
Selection Notes
Select this component when a fixed 5 V reference is required in space-constrained designs. The SOT-23 form factor suits high-density PCB layouts. Consider the 150 ppm/°C temperature coefficient for thermal stability requirements. Verify that the 70 µA operating current aligns with low-power system constraints.
Part Context
This part belongs to the LM4040 family of micropower shunt voltage references. The series offers various fixed voltage options and accuracy grades. The LM4040DIM3X-5.0/NOPB specifically denotes the 5 V version in the DIM3X package variant, providing a cost-effective solution for general-purpose precision applications.
Replacement Considerations
LM4040DIM3X-5.0/NOPB serves as a direct replacement for older National Semiconductor versions. Check for equivalent parts within the LM4040 series offering different accuracy or voltage levels if specifications allow.
