TL4050C50QDCKR

Overview

The TL4050C50QDCKR 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 of -40°C to +125°C and is housed in a SC-70-5 surface-mount package.

Feature Summary

• Provides stable 5 V reference output with ±0.5% initial accuracy
• Operates across extended industrial temperature range up to 125°C
• Designed for low-power applications with micropower consumption

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement systems
• Data acquisition circuits

Procurement Notes

Verify the exact suffix DCKR corresponds to the SC-70-5 tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management aligns with the specified operating temperature limits during high-current operation.

Selection Notes

Select this component when a 5 V fixed reference with ±0.5% tolerance is required in a compact SC-70-5 footprint. Consider the 50 ppm/°C temperature coefficient for environmental stability needs. Verify that the 15 mA maximum shunt current meets the circuit's biasing requirements without exceeding power dissipation limits.

Part Context
