LM4040DELT-5.0

Overview

The LM4040DELT-5.0 is a micropower shunt voltage reference manufactured by STMicroelectronics, providing a fixed 5.0 V output with ±1% initial accuracy at 25 °C. It operates within an industrial temperature range of -40 °C to +125 °C and features a maximum temperature coefficient of 70 ppm/°C. The device maintains stability when used with capacitive loads and exhibits very low low-frequency noise, typically 10 µVp-p. Designed for space-constrained applications, it is available in SOT23-3L and SOT323-5L packages.

Feature Summary

Procurement Notes

Verify the specific ordering code against official documentation to ensure correct package type (SOT23-3L or SOT323-5L) and tolerance level. Confirm that the selected variant meets the required thermal and electrical specifications for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring a stable 5.0 V reference with minimal power consumption. Ensure the design accommodates the specified operating current range and thermal constraints. Verify compatibility with existing PCB footprints for the chosen package style during the selection process.

Part Context

The LM4040 series consists of low-power, high-accuracy shunt voltage references designed for industrial environments. These devices offer fixed output voltages ranging from 2.048 V to 5.0 V with various accuracy grades. The series is optimized for compact designs using small surface-mount packages while maintaining robust performance across wide temperature ranges.
