LM4040A30IDBZT

Overview

The LM4040A30IDBZT is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 3V with an initial accuracy of ±0.1%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 100 ppm/°C. It draws a typical quiescent current of 45 µA and supports a maximum cathode current of 15 mA. The component is housed in a surface-mount SOT-23-3 package.

Feature Summary

Delivers high-precision voltage regulation with ±0.1% initial accuracy for stable reference applications.
Operates with ultra-low power consumption, drawing only 45 µA to extend battery life in portable devices.
Utilizes a compact SOT-23-3 surface-mount package for efficient space-constrained PCB layouts.

Applications

Portable instrumentation requiring low-power precision references
Battery-powered measurement systems
Data acquisition circuits

Procurement Notes

Verify the specific suffix 'IDBZT' against the manufacturer's latest datasheet to confirm pinout compatibility and marking codes. Ensure the sourcing channel provides original components with traceable documentation to avoid counterfeit risks. Confirm RoHS compliance status matches project requirements before finalizing procurement orders.

Selection Notes

Select this component when a 3V reference with ±0.1% tolerance is required. Compare the 100 ppm/°C temperature coefficient against application thermal stability needs. Verify that the 45 µA operating current aligns with system power budgets. Ensure the SOT-23-3 footprint fits the design constraints.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references from Texas Instruments. The series offers various fixed voltage options and accuracy grades (A, B, C) in small packages. The 'A' grade denotes the highest precision tier within this specific product line.
