LM4040DECT-2.5

Overview

The LM4040DECT-2.5 is a precision micropower shunt voltage reference manufactured by STMicroelectronics, providing a fixed 2.5 V output with ±1% initial accuracy at 25 °C. It operates within an industrial temperature range of -40 to +125 °C and features a maximum temperature coefficient of 70 ppm/°C. The device utilizes SOT323-5L surface-mount packaging and maintains stability when driving capacitive loads.

Feature Summary

Ultra-low operating current of 10 µA at 25 °C for power-constrained designs
Very low low-frequency noise typical value of 10 µVp-p
Stable operation when used with capacitive loads
Industrial temperature range from -40 °C to +125 °C

Applications

Portable battery-operated equipment
Data acquisition systems
Instrumentation

Procurement Notes

Verify the specific ordering suffix 'ECT' corresponds to the SOT323-5L package and tape-and-reel delivery format as defined in the official datasheet ordering table. Confirm that the 'D' grade designation aligns with the required ±1% precision specification for your application before finalizing procurement orders.

Selection Notes

Select this component when space-saving SOT323-5L packaging is required alongside 1% precision requirements. Ensure the design accommodates the minimum operating current of 10 µA and verify thermal dissipation limits within the specified junction temperature range for reliable long-term performance.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The family offers various fixed output voltages including 2.048 V, 3.0 V, 4.096 V, and 5.0 V, available in multiple precision grades (A, B, C, D) and packages (SOT23-3L, SOT323-5L).
