LM4041BIDBZT

Voltage Reference Overview

The LM4041BIDBZT is a micropower shunt voltage reference IC manufactured by Texas Instruments. It operates within the LM4041 series and utilizes a SOT-23-3 surface-mount package with three pins. The device provides an adjustable output voltage ranging from a minimum of 1.233 V up to 10 V. It features an initial accuracy tolerance of ±0.2% and a temperature coefficient of 100 ppm/°C. The component supports a maximum cathode current of 80 µA and delivers an output current capability of 12 mA. It functions reliably across an operating temperature range of -40°C to 85°C.

Voltage Reference Feature Summary

• Adjustable output voltage configuration spanning from 1.233 V to 10 V
• High precision performance with ±0.2% initial accuracy tolerance
• Micropower operation suitable for battery-powered applications

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• Portable instrumentation requiring low power consumption
• Battery-operated measurement systems

Voltage Reference Procurement Notes

Verify the specific suffix 'IDBZT' corresponds to the SOT-23-3 package and tape-and-reel delivery format. Confirm that the B-grade accuracy rating meets circuit requirements. Ensure compatibility with RoHS3 standards and check for any recent product change notices affecting marking or assembly origin before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when high accuracy is required alongside minimal quiescent current. The adjustable output allows flexibility in setting reference levels without external resistors if configured correctly. Compare against fixed-voltage alternatives if the application demands a specific static reference level rather than a configurable one. Consider thermal management within the small SOT-23 footprint.

Voltage Reference Part Context

This part belongs to the LM4041 family of micropower shunt references, which are designed to replace Zener diodes in precision applications. The family offers various accuracy grades and packages. The LM4041BIDBZT specifically represents the B-grade accuracy variant in a compact surface-mount form factor, targeting space-constrained designs needing stable voltage references.

Voltage Reference Replacement Considerations

LM4041CIDBZT offers similar functionality with ±0.5% accuracy. LM4041A12IDBZR provides a fixed 1.2V output with higher precision.
