TL4050C50IDBZT

Overview

The TL4050C50IDBZT 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 0.5%. The device features a temperature coefficient of 50 PPM/C and supports a maximum shunt current of 15 mA. It operates within a temperature range from -40°C to +125°C and is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Provides stable 5 V reference output with 0.5% initial accuracy
• Operates over extended industrial temperature range up to 125°C
• Compact three-terminal SOT-23 surface-mount packaging

Applications

• Portable battery-powered instrumentation
• Data acquisition systems requiring precise voltage references
• Industrial process control loops

Procurement Notes

Verify the specific suffix IDBZT corresponds to the cut tape or reel configuration required for your assembly line. Confirm that the 0.5% accuracy grade meets your circuit tolerance requirements compared to higher precision variants. Ensure the SOT-23-3 footprint matches your PCB design guidelines and thermal management strategy.

Selection Notes

Select this component when a 5 V reference with moderate 0.5% accuracy is sufficient for cost-sensitive applications. Consider the 50 PPM/C temperature coefficient for environments with significant thermal fluctuations. Compare against TL4050A series if tighter 0.1% accuracy is needed, or TL4050B series for 0.2% accuracy at potentially different cost points.

Part Context

This part belongs to the TL4050 family of micropower shunt voltage references from Texas Instruments. The family offers various output voltages and accuracy grades (A, B, C) in small packages like SOT-23 and SC-70. The 'C' designation indicates the 0.5% accuracy tier, while '50' specifies the 5 V output and 50 PPM/C tempco.
