Voltage Reference datasheet and documents for LM4120IM5X-2.5/NOPB

LM4120IM5X-2.5/NOPB

Voltage Reference Overview

The LM4120IM5X-2.5/NOPB is a micropower shunt voltage reference from Texas Instruments, housed in an SOT-23-5 package. It provides a fixed output of 2.5V with an initial accuracy of ±0.5%. The device operates within an input voltage range of 2V to 12V and draws a supply current of 275µA. Key performance metrics include a temperature coefficient of 50ppm/°C, low noise of 20µVp-p (0.1Hz to 10Hz), and operation across a temperature range of -40°C to 85°C.

Voltage Reference Feature Summary

Micropower series voltage reference designed for space-constrained applications
Low dropout operation allows use with minimal input-to-output voltage difference
High precision stability with low temperature coefficient for accurate referencing

Voltage Reference Applications

Portable instrumentation requiring stable reference voltages
Battery-powered measurement systems
Data acquisition systems

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free/RoHS compliance as per manufacturer documentation. Confirm the 'X' suffix denotes tape-and-reel packaging format. Ensure the part number matches the exact 2.5V output variant. Cross-reference the datasheet revision to confirm electrical characteristics have not changed. Validate that the SOT-23-5 footprint matches your PCB design requirements.

Voltage Reference Selection Notes

Select this component when a fixed 2.5V reference is required with low power consumption. The SOT-23-5 package suits surface-mount designs with limited board space. Consider the 275µA quiescent current for battery life calculations. Verify that the 50ppm/°C drift meets your system's thermal stability needs compared to lower-drift alternatives.

Voltage Reference Part Context

This part belongs to the LM4120 family of precision micropower voltage references. The family offers various fixed output voltages and accuracy grades. The IM5X designation specifies the industrial temperature range and reel packaging. It serves as a stable reference for ADCs, DACs, and comparators in analog signal chains.
