LM4120IM5X-2.0/NOPB

Voltage Reference Overview

The LM4120IM5X-2.0/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, housed in an SOT-23 package. It provides a nominal output voltage of 2.048 V with an initial accuracy of ±0.5%. The device operates within a temperature range of -40°C to +85°C and features a maximum input voltage of 14 V. It draws a typical supply current of 175 µA and supports a maximum shunt current of 5 mA.

Voltage Reference Feature Summary

• Provides stable precision voltage reference performance in a compact surface-mount package
• Designed for low-power applications through micropower consumption characteristics
• Capable of operating across extended industrial temperature ranges

Voltage Reference Applications

• Portable battery-powered instrumentation
• Data acquisition systems requiring precise voltage references
• Handheld meters and measurement devices

Voltage Reference Procurement Notes

Verify the specific suffix 'X' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status as indicated by the NOPB suffix. Check current lifecycle status as some variants may be discontinued or subject to limited availability constraints from the manufacturer.

Voltage Reference Selection Notes

Select this component when a fixed 2.048 V reference is required in space-constrained designs. Ensure the 5 mA maximum shunt current meets load requirements. Verify that the ±0.5% initial accuracy satisfies system tolerance needs compared to higher precision alternatives.

Voltage Reference Part Context

This part belongs to the LM4120 series of micropower shunt voltage references. It serves as a cost-effective alternative to zener diodes, offering superior stability and lower noise. The series is widely used in general-purpose analog circuits where moderate precision and low power are prioritized.

Voltage Reference Replacement Considerations

LM4120AIM5-2.0/NOPB offers improved ±0.2% accuracy. LM4120DM5-2.0/NOPB provides similar performance in a smaller SC-70 package. Verify pinout compatibility before substitution.
