LM4050AIM3-2.0/NOPB

Voltage Reference Overview

The LM4050AIM3-2.0/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, housed in an SOT-23-3 surface-mount package. It provides a fixed output voltage of 2.0 V with an initial accuracy of ±0.1%. The device features a low temperature coefficient of 50 ppm/°C and operates within a junction temperature range of -40°C to +125°C. Key electrical specifications include a maximum shunt current of 15 mA and a minimum cathode current of 65 µA. The component is RoHS compliant and lead-free.

Voltage Reference Feature Summary

• Provides high-precision voltage regulation with ±0.1% initial accuracy for stable reference applications.
• Features low power consumption with a typical cathode current of 65 µA, suitable for battery-powered systems.
• Designed for wide thermal stability with a temperature coefficient of 50 ppm/°C across industrial temperatures.

Voltage Reference Applications

• Portable instrumentation requiring precise voltage references
• Battery-operated measurement devices
• Data acquisition systems

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering part number matches the required tolerance grade (A) and output voltage (2.0V). Confirm packaging options such as cut tape or reel availability directly with authorized distributors to align with production requirements.

Voltage Reference Selection Notes

Select this component when a compact SOT-23-3 footprint is required alongside high accuracy. The 2.0 V output is ideal for single-supply ADCs. Consider the 65 µA minimum operating current to ensure proper biasing in low-power designs. Verify that the 15 mA maximum shunt current meets the load requirements of the target circuit.

Voltage Reference Part Context

This device belongs to the LM4050 series of micropower shunt voltage references from Texas Instruments. The series offers multiple reverse breakdown voltages in small packages. The 'A' designation indicates the tighter ±0.1% accuracy grade compared to standard grades. The 'M3' suffix denotes the SOT-23-3 package type.

Voltage Reference Replacement Considerations

Direct substitutes within the same family include LM4050AIM3X-2.0/NOPB. Other variants like LM4050AIM3-2.5/NOPB offer different output voltages but share similar performance characteristics. Verify pinout compatibility and thermal specifications before substitution.
