LM4040A50IDBZTG4

Overview

The LM4040A50IDBZTG4 is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 5V with an initial accuracy of 0.1% and a maximum temperature coefficient of 100ppm/°C. The device operates within a cathode current range of 45μA to 15mA and functions across an ambient temperature range of -40°C to 85°C. Packaged in a space-saving SOT-23-3 format, it requires no external capacitors for stability.

Feature Summary

• Delivers high-precision voltage regulation with tight output tolerances and low temperature drift characteristics.
• Operates efficiently at micropower levels while maintaining stability across wide variations in operating current and temperature.
• Functions reliably without the need for external output capacitors due to inherent stability with all capacitive loads.

Applications

• Data-Acquisition Systems
• Energy Infrastructure
• Analog Input Modules
• Field Transmitters

Procurement Notes

Verify the specific suffix 'TG4' against the manufacturer's latest documentation to confirm RoHS compliance and package details. Ensure the ordering code matches the required industrial temperature grade and tolerance specifications for your design requirements before finalizing procurement.

Selection Notes

Select this component when a stable 5V reference is needed in compact designs requiring minimal external components. It is suitable for applications demanding high accuracy over varying temperatures where power consumption must remain low. Verify that the load current stays within the recommended operating range to maintain specified performance metrics.

Part Context

This part belongs to the LM4040 series of shunt voltage references from Texas Instruments. The series offers various fixed output voltages and grades (A, B, C, D) to balance cost and performance. The 'A' grade specifically denotes the highest precision tier available in this family, characterized by the tightest initial accuracy and temperature coefficients.
