LM4050QBIM3-2.5/NOPB

Voltage Reference Overview

The LM4050QBIM3-2.5/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, housed in a SOT-23-3 package. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.2%. The device features a temperature coefficient of 50 ppm/°C and operates within a junction temperature range of -40°C to +125°C. It is qualified under the AEC-Q100 standard for automotive applications. The component draws a typical cathode current of 65 µA and supports a maximum shunt current of 15 mA.

Voltage Reference Feature Summary

Provides stable reference voltage with high precision tolerance
Designed for low power consumption in battery-operated systems
Qualified for automotive reliability standards

Voltage Reference Applications

Automotive electronic control units
Portable measurement instruments
Data acquisition systems

Voltage Reference Procurement Notes

Verify the specific suffix 'QBI' corresponds to the required ±0.2% accuracy grade and automotive qualification status. Confirm the package marking matches the SOT-23-3 outline drawing. Ensure the order specifies the NOPB lead-free designation if RoHS compliance is mandatory for the assembly process.

Voltage Reference Selection Notes

Select this variant when a 2.5 V reference with tighter initial accuracy than the standard B-grade is required. The Q-grade designation indicates improved initial accuracy compared to lower grades. Consider the 65 µA quiescent current for power-sensitive designs. Verify that the 15 mA maximum shunt current meets the load requirements of the circuit design.

Voltage Reference Part Context

This component belongs to the LM4050-N family of micropower shunt voltage references. The family offers various fixed output voltages and accuracy grades. The QB designation specifically denotes the automotive-qualified version with enhanced initial accuracy specifications compared to commercial variants.
