TL431IDBVTE4

Overview

The TL431IDBVTE4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 2.495 V to 36 V and provides an initial accuracy of ±2.2%. The device supports a maximum cathode current of 1 mA and a maximum output current of 100 mA. It functions across a temperature range of -40°C to +85°C with a typical temperature coefficient of 92 ppm/°C. The component utilizes a 5-pin SOT-23 (SC-74A) surface-mount package.

Feature Summary

Adjustable precision reference voltage capability
Low dynamic impedance for stable regulation
Wide operating temperature range suitability

Applications

Precision voltage references in power supplies
Programmable linear regulators
Feedback control loops in switching converters

Procurement Notes

Verify the specific suffix 'E4' against official Texas Instruments documentation to confirm lead-free status and RoHS compliance details. Confirm that the SOT-23-5 package designation matches the required PCB footprint. Ensure the ±2.2% accuracy grade meets system requirements, as other grades exist within the family. Check for any obsolescence notices or lifecycle changes associated with this specific revision code.

Selection Notes

Select this component when a low-cost, adjustable shunt regulator with moderate accuracy is required. The SOT-23-5 package offers space efficiency compared to larger through-hole options. Consider the ±2.2% tolerance if tighter specifications are not critical. Evaluate thermal management needs based on the maximum cathode current limits and ambient operating conditions.

Part Context

This part belongs to the TL431 family of programmable shunt regulators, widely used as voltage references. It serves as a cost-effective alternative to Zener diodes in feedback networks. The device integrates a bandgap reference and error amplifier to maintain precise output voltage regulation across varying load and temperature conditions.
