LM4120AIM5X-2.0

Voltage Reference Overview

The LM4120AIM5X-2.0 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 2.0 V with an initial accuracy of ±0.2%. The device operates within an input voltage range of 2 V to 12 V 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 reference 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 systems needing precise analog references

Voltage Reference Procurement Notes

Verify the specific suffix 'X' indicates tape and reel packaging configuration when ordering. Confirm that the 'A' grade designation corresponds to the required ±0.2% initial accuracy specification for your design. Ensure the operating environment remains within the specified -40°C to +85°C temperature range to maintain performance guarantees.

Voltage Reference Selection Notes

Select this component when a fixed 2.0 V reference is required with high precision in a compact surface-mount package. It is suitable for designs prioritizing low power consumption and stability over wide temperature variations. Consider the 5 mA output capability against your load requirements to ensure adequate drive strength without exceeding limits.

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 AIM5X variant specifically denotes the A-grade accuracy version in an SOT-23 package supplied in reel format, targeting space-constrained and battery-operated electronic applications.

Voltage Reference Replacement Considerations

Check for LM4120AIM5-2.0/NOPB as a potential alternative if reel packaging is not strictly required, noting differences in shipping format. Verify compatibility with other LM4120 variants offering different output voltages or accuracy levels if system constraints allow.
