LM4040BECT-2.0

Overview

The LM4040BECT-2.0 is a low-power, high-accuracy shunt voltage reference manufactured by STMicroelectronics. It provides a fixed output voltage of 2.048V with an initial accuracy tolerance of ±0.2%. The device features a maximum temperature coefficient of 70ppm/°C and operates within an industrial temperature range of -40°C to +125°C. It supports a cathode current of 12µA and delivers up to 15mA output current. The component is housed in a SOT-323-5 surface-mount package.

Feature Summary

Ultra-low operating current of 10µA at 25°C for power-constrained designs
High precision with ±0.2% initial accuracy at 25°C
Very low low-frequency noise typical value of 10µVp-p
Stable operation when used with capacitive loads

Applications

Portable battery-powered equipment
Data acquisition systems
Instrumentation

Procurement Notes

Verify the specific suffix ECT corresponds to the SOT-323-5L package configuration as documented in official STMicroelectronics datasheets. Confirm that the B grade designation aligns with the required ±0.2% initial accuracy specification for the target application. Ensure environmental compliance requirements such as RoHS3 are met before finalizing procurement orders.

Selection Notes

Select this component for applications requiring precise voltage referencing in space-constrained environments due to its compact SOT-323-5L footprint. The low quiescent current makes it suitable for battery-operated devices where power efficiency is critical. Consider the 70ppm/°C temperature coefficient for stability across the specified industrial temperature range.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references from STMicroelectronics. The series offers various fixed output voltages including 2.048V, 2.5V, 3.0V, 4.096V, and 5.0V. Different accuracy grades (A, B, C, D) are available to meet varying precision requirements while maintaining the same low-power characteristics and industrial temperature range capabilities.
