TL4050A50IDBZR

Overview

The TL4050A50IDBZR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 5 V with an initial accuracy of 0.1% and a temperature coefficient of 50 PPM/°C. The device operates within a junction temperature range of -40°C to 85°C and supports a maximum cathode current of 15 mA with a minimum operating current of 74 µA. It is housed in a compact SOT-23-3 surface-mount package, designed for applications requiring stable voltage references in space-constrained environments.

Feature Summary

• Provides high-precision voltage regulation with 0.1% initial accuracy
• Operates efficiently at micropower levels with low minimum current consumption
• Maintains stability across industrial temperature ranges

Applications

• Portable instrumentation systems
• Battery-powered measurement devices
• Data acquisition systems

Procurement Notes

Verify the specific suffix IDBZR confirms the SOT-23-3 package and tape-and-reel delivery format. Confirm the 'A' grade designation matches the required 0.1% accuracy specification for your design. Ensure the thermal management plan accounts for the specified operating temperature limits during continuous operation.

Selection Notes

Select this component when a 5 V reference with tight tolerance is required in a small footprint. Compare against LM4040 variants if higher temperature ratings or different accuracy grades are needed. Evaluate power budget constraints against the 74 µA minimum current requirement to ensure proper shunt operation under all load conditions.

Part Context

This part belongs to the TL4050 family of micropower shunt references from Texas Instruments. The family offers various voltage options and accuracy grades packaged in SOT-23 and SC-70 formats. The TL4050 series is engineered to replace larger discrete reference solutions while maintaining precision in portable and battery-operated electronics.

Replacement Considerations

LM4040A50IDBZR serves as a functional alternative within the same package and voltage class.
