Overview
The LM4030CMFX-2.5/NOPB is an ultra-high-precision shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.15% and a temperature coefficient of 30 PPM/C. The device operates within a junction temperature range of -40°C to +125°C and supports a maximum shunt current of 50 mA. It is housed in a compact SOT-23-5 surface-mount package, designed for applications requiring stable reference voltages in space-constrained environments.
Feature Summary
- Ultra-high precision performance with tight initial accuracy tolerances
- Low temperature coefficient ensures stable voltage output across wide thermal ranges
- Compact SOT-23-5 package facilitates high-density circuit board layouts
Applications
- Portable instrumentation requiring precise analog-to-digital conversion references
- Battery-powered measurement devices needing low power consumption
- Data acquisition systems utilizing high-resolution ADCs
Procurement Notes
Verify the complete part number including the suffix to ensure correct voltage and tolerance specifications. Confirm RoHS compliance status as indicated in official documentation. Check for any specific handling requirements related to moisture sensitivity levels before assembly. Ensure compatibility with existing PCB footprints for the SOT-23-5 package.
Selection Notes
Select this component when high accuracy and stability are critical for signal integrity. Consider the 50 mA maximum shunt current limit for power dissipation calculations. Evaluate the 30 PPM/C temperature coefficient against environmental operating conditions. Compare package size constraints with alternative reference types if space is limited.
Part Context
This device belongs to the LM4030 series of micropower shunt voltage references from Texas Instruments. The series is characterized by its ability to provide precise reference voltages in small packages. It serves as a key component in power management integrated circuits (PMIC) for maintaining voltage stability in electronic systems.
Replacement Considerations
Consult official substitution guides for compatible parts within the same family or equivalent performance tiers. Verify pinout compatibility and electrical parameter alignment before replacing.
