LM4050CIM3-2.0/NOPB

Voltage Reference Overview

The LM4050CIM3-2.0/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, featuring a nominal output voltage of 2.048 V. It operates within an extended temperature range from -40°C to +125°C and utilizes a SOT-23-3 surface-mount package. The device offers an initial accuracy of ±0.5% and maintains a low temperature coefficient of 50 ppm/°C. Designed for high stability, it supports a maximum cathode current of 15 mA while consuming minimal quiescent current, making it suitable for space-constrained applications requiring reliable voltage regulation.

Voltage Reference Procurement Notes

Verify the specific suffix 'CIM3' corresponds to the required accuracy grade and temperature rating. Confirm the 'NOPB' designation indicates lead-free and RoHS compliance. Ensure the SOT-23-3 package matches the PCB footprint requirements. Check for any recent product change notices affecting electrical characteristics or manufacturing sites.

Voltage Reference Selection Notes

Select this component when a fixed 2.048 V reference is needed in a compact SOT-23-3 package. It is appropriate for designs requiring ±0.5% initial accuracy and operation up to 125°C. Consider alternatives if lower temperature coefficients or higher accuracy grades are required for the specific application environment.

Voltage Reference Part Context

This part belongs to the LM4050 family of precision micropower shunt voltage references. The LM4050 series is designed to replace older zener diodes in various applications. It offers improved performance in terms of noise, temperature drift, and long-term stability compared to traditional discrete solutions.

Voltage Reference Replacement Considerations

LM4050AIM3-2.0/NOPB: Offers tighter initial accuracy (±0.1%) but may have different availability. LM4040CIM3-2.0/NOPB: Lower cost option with wider temperature coefficient (150 ppm/°C) and limited to 85°C max temperature.
