LM4130CIM5-2.0

Voltage Reference Overview

The LM4130CIM5-2.0 is a precision micropower shunt voltage reference from Texas Instruments, featuring an initial accuracy of ±0.2% and a low temperature coefficient of 15 ppm/°C. It operates within a supply voltage range of 2.5V to 20V and maintains a typical dynamic impedance of 0.06Ω. The device draws a quiescent current of 75µA and supports a load current up to 8mA. Packaged in the SOT-23-5 (CIM5) format, it ensures stable regulation across industrial temperature ranges.

Voltage Reference Procurement Notes

Verify the complete part number including suffixes such as tape-and-reel indicators or specific temperature grades when ordering. Confirm that the SOT-23-5 package matches your PCB footprint requirements. Ensure compatibility with your system's voltage range and current demands before procurement.

Voltage Reference Selection Notes

Select this component when both high precision and low power consumption are required. The ±0.2% accuracy makes it suitable for applications where standard references lack sufficient tolerance. Consider the 75µA quiescent current if battery efficiency is a priority compared to higher current alternatives.

Voltage Reference Part Context

This device belongs to the LM4130 family of micropower shunt references. It shares architectural similarities with other precision references but distinguishes itself through its specific combination of ultra-low quiescent current and tight initial accuracy. The CIM5 suffix denotes the SOT-23-5 surface-mount package variant.

Voltage Reference Replacement Considerations

Direct replacements include other LM4130 variants with different output voltages or packages. Cross-reference with LM4040 series for similar performance levels, ensuring pinout compatibility and electrical specifications match the original design requirements.
