LM4120IM5X-4.1/NOPB

Voltage Reference Overview

The LM4120IM5X-4.1/NOPB is a precision micropower low dropout voltage reference manufactured by Texas Instruments, housed in an SOT-23 package. It provides a fixed output voltage of 4.1V with an initial accuracy of 0.5%. The device operates within a temperature range of -40°C to +85°C and features a maximum shunt current of 5 mA.

Voltage Reference Feature Summary

• Precision micropower operation designed for space and power-sensitive applications
• Low dropout capability ensures stable regulation across varying input voltages
• High initial accuracy maintains precise output voltage stability

Voltage Reference Applications

• Portable instrumentation requiring low power consumption
• Battery-powered measurement systems
• Data acquisition systems needing stable reference voltages

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance status as per the manufacturer's datasheet. Confirm the 'IM5X' designation corresponds to the correct industrial temperature grade and tape-and-reel packaging format before procurement. Ensure the 4.1V output variant matches the circuit design requirements exactly.

Voltage Reference Selection Notes

Select this component when a fixed 4.1V reference is required with 0.5% initial accuracy. Consider the 5 mA maximum shunt current limit for load driving capabilities. Verify that the SOT-23 package fits the PCB layout constraints and that the -40°C to +85°C operating range meets the environmental specifications of the target application.

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 'IM5X' suffix typically denotes the industrial temperature range and surface-mount packaging, while 'NOPB' signifies non-plated-lead (lead-free) construction compliant with environmental standards.

Voltage Reference Replacement Considerations

Check for direct pin-compatible alternatives within the LM4120 family offering different output voltages or accuracies. Verify if other manufacturers provide equivalent 4.1V references with similar power and accuracy specifications.
