LM4040C30FTA

Overview

The LM4040C30FTA is a precision micro-power shunt voltage reference manufactured by Diodes Incorporated. It provides a fixed output voltage of 3.0V with an initial tolerance of ±0.5% at +25°C. The device operates within a wide current range from 60µA to 15mA and maintains stability over an extended temperature range of -40°C to +125°C. It features a maximum average temperature coefficient of 100 ppm/°C and utilizes a compact SOT23 surface-mount package.

Feature Summary

Provides stable reference voltage in a small SOT23 surface-mount package
Operates effectively across a wide current range from 60µA to 15mA
Maintains high precision with low temperature coefficient over industrial temperatures
Designed for high capacitive load tolerance without requiring output capacitors

Applications

Battery powered equipment
Precision power supplies
Portable instrumentation
Data acquisition systems

Procurement Notes

Verify the specific C-grade designation ensures the required 0.5% initial accuracy for your design. Confirm that the SOT23 package footprint matches your PCB layout, noting that Pin 3 must be left floating or connected to Pin 2 due to internal die attachment. Ensure operating conditions remain within the specified 60µA to 15mA current limits to maintain performance specifications.

Selection Notes

Select this component when space constraints require a small SOT23 package while maintaining precision voltage reference capabilities. It is suitable for designs needing a 3.0V reference with moderate accuracy requirements compared to higher-grade options. Consider the thermal characteristics and ensure adequate heat dissipation if operating near maximum current limits in confined spaces.

Part Context

This part belongs to the LM4040 family of bandgap circuits designed for precision applications. The 'C' suffix indicates a 0.5% initial tolerance grade, distinguishing it from B-grade (0.2%) and D-grade (1%) variants. The '30' denotes the 3.0V output voltage, and 'FTA' specifies the SOT23 package with tape-and-reel packaging.
