TL431ACDBVRE4

Overview

The TL431ACDBVRE4 is an adjustable shunt voltage reference IC manufactured by Texas Instruments. It operates within a cathode voltage range of 2.495 V to 36 V and supports a maximum output current of 100 mA. The device features an initial accuracy of ±1% and a maximum temperature coefficient of 92 ppm/°C. It is housed in a surface-mount SOT-23 package with five pins, designed for operation between 0°C and 70°C.

Feature Summary

• Provides precise adjustable voltage regulation via a shunt topology suitable for feedback control loops.
• Delivers high initial accuracy of ±1% across the operating temperature range.
• Features low temperature drift characteristics to maintain stability under thermal variations.

Applications

• Precision voltage references in power supply circuits
• Feedback control elements in switching regulators
• Comparator applications requiring stable threshold voltages

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and check for specific manufacturing date codes or lot numbers if required for traceability. Ensure the ordering suffix matches the exact tape and reel specifications needed for automated assembly processes.

Selection Notes

Select this component when a compact surface-mount solution is required for adjustable voltage regulation. The SOT-23 package offers space efficiency compared to larger packages. Consider the ±1% tolerance and 100 mA current capability against circuit requirements before choosing over higher precision or higher current variants.

Part Context

This part belongs to the TL431 family of adjustable shunt regulators. It shares functional similarities with other members like the TL431ACD but differs in packaging and specific suffix designations. The 'E4' suffix typically indicates lead-free composition and environmental compliance consistent with RoHS standards.
