LM4040AIZ-5.0/NOPB

Overview

The LM4040AIZ-5.0/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 5.0 V. It features an initial accuracy of ±0.1% and operates within a temperature range of -40°C to +85°C. The device utilizes a TO-92 three-pin through-hole package. Key electrical characteristics include a maximum shunt current of 15 mA and a temperature coefficient of 100 ppm/°C. It is designed for applications requiring high precision in compact form factors.

Feature Summary

• Provides stable fixed voltage reference with high initial accuracy
• Micropower operation suitable for battery-powered systems
• Shunt regulator topology for simple circuit integration

Applications

• Precision measurement instrumentation
• Portable electronic devices
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free status and RoHS compliance as per manufacturer documentation. Confirm the 'A' grade designation corresponds to the ±0.1% initial accuracy specification. Ensure the TO-92 package type matches the target PCB footprint requirements before procurement.

Selection Notes

Select this component when a fixed 5.0 V reference with tight tolerance is required in a through-hole package. Compare against other grades in the LM4040 series if cost sensitivity outweighs the need for ±0.1% accuracy. Consider SOT-23 variants like the LM4040BIM3-5.0 if surface mount space is constrained.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The family offers various fixed output voltages and accuracy grades. The 'A' suffix typically denotes tighter initial accuracy compared to 'B' or 'C' grades. The 'I' indicates industrial temperature range operation.

Replacement Considerations

LM4040BIZ-5.0/NOPB offers similar functionality with ±0.2% accuracy. LM4040DIZ-5.0/NOPB provides lower cost with wider tolerance. Verify pinout compatibility and thermal performance when substituting.
