LM4120AIM5-3.0/NOPB

Voltage Reference Overview

The LM4120AIM5-3.0/NOPB is a precision micropower low dropout voltage reference manufactured by Texas Instruments, housed in an SOT-23-5 package. It provides a fixed output voltage of 3.0 V with an initial accuracy of ±0.2%. The device operates within an input voltage range of 2V to 12V and supports a maximum shunt current of 5 mA. It features a temperature coefficient of 50 PPM/°C and functions reliably across a temperature range of -40°C to +85°C.

Voltage Reference Feature Summary

• Provides high-precision fixed voltage output with tight initial accuracy tolerance
• Designed for micropower applications with low dropout operation characteristics
• Capable of sourcing up to 5 mA load current while maintaining regulation

Voltage Reference Applications

• Portable instrumentation requiring stable reference voltages
• Battery-powered measurement systems
• Data acquisition circuits needing precise analog references

Voltage Reference Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required pinout and electrical specifications. Check RoHS compliance status as indicated on official datasheets. Ensure storage conditions meet moisture sensitivity level requirements before assembly.

Voltage Reference Selection Notes

Select this component when a fixed 3.0 V reference with ±0.2% accuracy is required in a compact SOT-23-5 footprint. Consider the 50 PPM/°C temperature coefficient for thermal stability needs. Evaluate the 275 µA supply current against system power budgets. Verify input voltage compatibility within the 2V to 12V operating range.

Voltage Reference Part Context

This part belongs to the LM4120 series of precision micropower voltage references from Texas Instruments. The series offers various fixed output voltages and accuracy grades. The 'AIM5' designation indicates the industrial temperature grade and SOT-23-5 packaging. The '/NOPB' suffix denotes lead-free construction and absence of specific prohibited substances.

Voltage Reference Replacement Considerations

Direct substitutes include other LM4120 variants with different output voltages such as LM4120AIM5-2.0/NOPB or LM4120AIM5-5.0/NOPB, provided the voltage requirement changes. Cross-reference with LM4120IM5X series for reel-packaged alternatives if available.
