LM4040BIZ-5.0

Overview

The LM4040BIZ-5.0/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, formerly National Semiconductor. It provides a fixed output voltage of 5.0 V with an initial accuracy of ±0.2%. The device operates within an industrial temperature range of -40 °C to +125 °C and features a maximum temperature coefficient of 100 ppm/°C. It utilizes a TO-92 plastic package with three pins.

Feature Summary

• Provides stable 5.0 V output with high precision
• Operates across wide industrial temperature ranges
• Low power consumption suitable for sensitive designs

Applications

• Precision measurement systems
• Portable instrumentation
• Battery-powered equipment

Procurement Notes

Verify the manufacturer designation as Texas Instruments or National Semiconductor on the datasheet. Confirm the NOPB suffix indicates lead-free compliance. Ensure the B grade corresponds to the required ±0.2% accuracy and 100 ppm/°C temperature coefficient specifications for your design.

Selection Notes

Select this component when a fixed 5 V reference with ±0.2% accuracy is required in a through-hole TO-92 package. It is suitable for applications needing low current operation and stability over the full industrial temperature range. Consider SOT-23 variants if surface mount space is limited.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The 'B' suffix denotes ±0.2% initial accuracy, while 'IZ' typically indicates the TO-92 package style. The NOPB suffix confirms non-phosphorus lead-free construction compliant with RoHS standards.

Replacement Considerations

LM4040BIZ-50-NOPB is a confirmed substitute with identical electrical characteristics and packaging.
