LM4040D33FTA

Overview

The LM4040D33FTA is an automotive-compliant precision micropower shunt voltage reference manufactured by Diodes Incorporated. It provides a fixed output voltage of 3.3V with a D-grade initial tolerance of ±1% at +25°C. The device operates within a wide current range of 60µA to 15mA and maintains stability across an extended temperature range from -40°C to +125°C. Packaged in a compact SOT23 surface-mount format, it features a maximum temperature coefficient of 100 ppm/°C and low output noise.

Feature Summary

Automotive compliant design suitable for specific change control requirements
Capable of driving capacitive loads without requiring an output capacitor
Maintains excellent stability over a wide operating current range
Utilizes a small outline SOT23 package for space-constrained applications

Applications

Automotive reference voltages
Automotive data acquisition systems

Procurement Notes

Verify the component matches the exact automotive grade specification required for your application. Confirm that the manufacturer's quality standards align with your project's compliance needs. Ensure the ordering suffix corresponds to the correct packaging configuration. Validate all electrical parameters against the official datasheet before finalizing procurement decisions.

Selection Notes

Select this component when a stable 3.3V reference is needed in automotive environments. The D-grade tolerance offers a balance between precision and cost. Consider the SOT23 package size if board real estate is limited. Verify that the operating current range meets the system's power budget constraints.

Part Context

This part belongs to the LM4040Q family of bandgap circuits designed for high-precision voltage referencing. It serves as a pin-for-pin compatible alternative to industry standard references but is specifically qualified for automotive use. The family includes various voltage options and accuracy grades to suit different design requirements.
