TLV431TQFTA

Overview

The TLV431TQFTA is a three-terminal adjustable shunt regulator manufactured by Diodes Incorporated. It features an internal reference voltage of 1.24V and supports an output voltage range from 1.24V to 18V, set via external resistors. The device offers initial accuracy grades of 1%, operates within a temperature range of -40°C to +125°C, and draws a typical operating supply current of 55µA. It is AEC-Q100 qualified for automotive applications and housed in an SOT-23-3 package.

Feature Summary

Three-terminal adjustable shunt regulator design with excellent temperature stability
Automotive-grade qualification compliant with AEC-Q100 standards
Programmable output voltage capability using two external divider resistors
Low power consumption suitable for battery-operated systems

Applications

Isolated feedback loops for Switch Mode Power Supplies (SMPS)
Precision constant current sinks
Adjustable linear voltage regulators
Increasing output voltage of fixed linear regulators

Procurement Notes

Verify the specific suffix 'TQ' against official Diodes Incorporated documentation to confirm it denotes the required automotive grade and tolerance level. Ensure the ordering code matches the exact package type and reel specifications required for your assembly process. Cross-reference the datasheet revision date to ensure compliance with current manufacturing standards.

Selection Notes

Select this component when an AEC-Q100 qualified shunt regulator is required for automotive or high-reliability industrial designs. The 1.24V internal reference provides higher precision compared to standard 2.5V references. Consider the SOT-23-3 footprint constraints and the need for external resistors to define the precise output voltage within the 1.24V to 18V range.

Part Context

The TLV431 series serves as a low-cost, high-performance alternative to traditional Zener diodes and other shunt regulators. Manufactured by Diodes Incorporated, these devices are widely used in power management circuits where stable voltage referencing is critical. The family includes various packages and grades to suit different thermal and spatial requirements.

Replacement Considerations

Direct substitutes include the TLV431AQFTA and TLV431BQFTA from Diodes Incorporated, which share similar electrical characteristics and automotive qualification. Other manufacturers offer equivalent parts such as the LM4040 or REF30xx series, though pinouts and reference voltages may differ.
