LM4041CFTA

Overview

The LM4041CFTA is a precision micro-power shunt voltage reference manufactured by Diodes Incorporated. It provides a fixed output voltage of 1.225V with an initial tolerance of ±0.5% at +25°C. The device operates within a wide current range from 60µA to 12mA and features a maximum temperature coefficient of 100ppm/°C across the -40°C to +125°C extended temperature range. Packaged in a compact SOT23 surface-mount format, it offers low output noise of 20µVRMS (10Hz to 10kHz) and maintains stability without requiring external capacitors.

Feature Summary

Provides stable 1.225V reference output with high precision
Operates effectively across a wide current range from 60µA to 12mA
Maintains stability under capacitive loads without external components
Designed for space-constrained applications using small outline packages

Applications

Battery powered equipment
Precision power supplies
Portable instrumentation
Data acquisition systems

Procurement Notes

Verify that the specific ordering suffix matches the required package type and tolerance grade. Confirm the component meets the necessary environmental standards for the intended deployment environment. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 1.225V reference is required with tight initial accuracy. Consider the SOT23 package for limited board space availability. Evaluate the operating current range against system power constraints to ensure operation remains within the specified 60µA to 12mA limits for optimal performance.

Part Context

This part belongs to the LM4041 series of bandgap circuits designed for precision voltage referencing. It serves as a pin-for-pin compatible alternative to other variants within the family, offering both adjustable and fixed output options. The series supports various grades to balance cost and precision requirements for different application needs.
