LM4040C30IDCKR

Overview

The LM4040C30IDCKR is a precision micro-power shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 3 V with an initial accuracy of ±0.5%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 100 PPM/°C. It supports a maximum shunt current of 15 mA and requires a minimum cathode current of 95 µA for regulation. The component is housed in a compact SC-70-5 surface-mount package, suitable for space-constrained designs.

Feature Summary

Delivers stable 3 V reference voltage with high initial accuracy
Operates efficiently at low quiescent currents for battery applications
Maintains performance across industrial temperature ranges

Applications

Portable instrumentation requiring precise voltage references
Battery-powered measurement systems
Data acquisition circuits

Procurement Notes

Verify the specific suffix IDCKR corresponds to the SC-70-5 package and standard operating temperature range. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before integration. Ensure supply chain sources are authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a 3 V reference with ±0.5% tolerance is required in a small surface-mount footprint. Consider the 100 PPM/°C temperature coefficient for thermal stability needs. Verify that the circuit design can maintain the minimum 95 µA cathode current to ensure proper regulation under all load conditions.
