TL4050B50IDBZTG4

Overview

The TL4050B50IDBZTG4 is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 5V with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +125°C and features a low temperature coefficient of 50ppm/°C. It draws a cathode current of 80µA and supports a maximum shunt current of 15mA. The component is housed in a SOT-23-3 package.

Feature Summary

• Provides stable reference voltage with high initial accuracy
• Operates across extended industrial temperature ranges
• Designed for low power consumption applications

Applications

• Portable instrumentation circuits
• Battery-powered measurement systems
• Data acquisition signal conditioning

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the package type matches the design requirements. Ensure the operating temperature range aligns with the system environment. Check for any specific handling instructions regarding moisture sensitivity levels during assembly processes.

Selection Notes

Select this component when a fixed 5V reference with tight tolerance is required in a compact surface-mount package. Consider the 80µA quiescent current for battery life optimization. Evaluate the 50ppm/°C drift against long-term stability needs. Compare noise specifications if high-frequency performance is critical for the application.
