LM4041DILP

Voltage Reference Overview

The LM4041DILP is a micropower shunt voltage reference IC manufactured by Texas Instruments. It provides an adjustable output voltage ranging from 1.233 V to 10 V with an initial accuracy of ±1%. The device features a low temperature coefficient of 150 ppm/°C and operates within a junction current range of 80 µA to 12 mA. It utilizes a TO-92-3 through-hole package, measuring approximately 4.5 mm in length, 4.6 mm in width, and 4.5 mm in height. The component supports industrial operating temperatures from -40°C to +85°C and exhibits a typical output noise of 20 µVrms.

Voltage Reference Feature Summary

• Adjustable output voltage configuration using external resistors
• Stable operation across wide load current ranges
• Low dynamic impedance for precise regulation
• Through-hole mounting capability for robust connections

Voltage Reference Applications

• Data acquisition systems requiring stable reference voltages
• Portable battery-powered equipment due to low quiescent current
• Precision audio applications needing low noise performance
• Process control instrumentation and test equipment

Voltage Reference Procurement Notes

Verify the specific suffix and marking code against the manufacturer's latest datasheet to confirm tolerance grade and temperature range. Ensure the TO-92-3 package dimensions match the PCB footprint requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly. Confirm availability as some variants may be subject to production changes or end-of-life notices.

Voltage Reference Selection Notes

Select this component when an adjustable shunt reference is required in a through-hole design. It is suitable for applications demanding high precision at low currents. Consider the 1% tolerance and 150 ppm/°C coefficient against stricter requirements. Evaluate space constraints as the TO-92 package is larger than surface-mount alternatives like SOT-23 or SC-70.

Voltage Reference Part Context

The LM4041DILP belongs to the LM4041 family of micropower shunt voltage references. This series offers both fixed (1.225 V) and adjustable output options. The family is designed for space-saving applications and power-restricted designs. Other packages in the series include SOT-23-3L and SC-70-5L for surface mount implementations.
