TLV431BIDBVTG4

Overview

The TLV431BIDBVTG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It features an initial accuracy of 0.5% and operates within a temperature range of -40°C to 85°C. The device provides an adjustable output voltage from 1.24V to 6V with a maximum input voltage of 7V. It supports a maximum cathode current of 15mA and has a typical temperature coefficient of 138ppm/°C. The component is housed in a 5-pin SOT-23 package designed for surface-mount applications.

Feature Summary

• Provides high-precision voltage regulation with 0.5% initial accuracy
• Enables flexible design through wide adjustable output voltage range
• Supports surface-mount integration via compact SOT-23-5 packaging

Applications

• Battery-powered portable equipment requiring precise voltage references
• Low-voltage power supply circuits needing stable regulation
• Comparator reference voltage generation in signal conditioning systems

Procurement Notes

Verify the specific suffix 'TG4' indicates lead-free compliance and RoHS standards when sourcing. Confirm the SOT-23-5 package variant matches the PCB footprint requirements. Ensure the operating temperature range of -40°C to 85°C aligns with the target application environment. Cross-check the 0.5% accuracy grade against system tolerance specifications to guarantee performance reliability.

Selection Notes

Select this component when a low-voltage, high-accuracy reference is required in space-constrained designs. The 15mA current capability suits moderate load applications without external amplification. Consider the 138ppm/°C temperature coefficient for thermal stability needs. Compare against higher-current variants if load demands exceed standard shunt limits.

Part Context

This part belongs to the TLV431B family of low-voltage adjustable precision shunt regulators. It serves as a direct replacement for standard TL431 devices in low-voltage applications where lower input voltage operation is necessary. The family offers improved performance over traditional references while maintaining pin compatibility for many legacy designs.

Replacement Considerations

Direct substitutes include other TLV431B series variants with compatible packages. Verify equivalent accuracy grades and temperature ranges when selecting alternatives. Check for identical pinout configurations to ensure seamless board-level integration without schematic modifications.
