Overview
The LM4040D50FTA is a precision micro-power shunt voltage reference manufactured by Diodes Incorporated. It provides a fixed output voltage of 5.0V with an initial tolerance of ±1% at +25°C. The device operates within a wide current range from 60µA to 15mA and features a maximum temperature coefficient of 100 ppm/°C. Designed for surface mount applications, it utilizes the SOT-23 package. The component supports an extended operating temperature range from -40°C to +125°C.
Feature Summary
- Provides stable 5.0V reference in compact SOT-23 surface mount package
- Operates across wide current range without external output capacitor
- Maintains stability under capacitive loads
- Compliant with RoHS standards and free of halogens and antimony
Applications
- Battery powered equipment
- Precision power supplies
- Portable instrumentation
- Data acquisition systems
Procurement Notes
Verify the specific D-grade tolerance requirement against application needs. Confirm that the SOT-23 package dimensions match the PCB footprint. Ensure the operating environment stays within the specified -40°C to +125°C range. Check datasheet for minimum operating current requirements relative to load conditions.
Selection Notes
Select this part when a 5.0V reference with 1% accuracy is sufficient. Consider B or C grades if tighter tolerances are required. Verify that the circuit can maintain current between 60µA and 15mA. Evaluate thermal dissipation capabilities within the SOT-23 package constraints.
Part Context
This component belongs to the LM4040 family of bandgap circuits. The family includes variants with 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V outputs. Grades B, C, and D offer varying initial tolerances. The SC70-5 variant is listed as End of Life.
Replacement Considerations
LM4040B50FTA offers 0.2% tolerance. LM4040C50FTA offers 0.5% tolerance. Both share the same package and pinout.
FAQ
How should Pin 3 be handled in the SOT-23 package?
Pin 3 must be left floating or connected to Pin 2 due to electrical contact between them.
Is an output capacitor required for stability?
No, the device is designed to be highly tolerant of capacitive loads and does not require an output capacitor.
