TLV431CDBVTG4

Overview

The TLV431CDBVTG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It provides an output voltage range from 1.24 V to 6 V with an initial accuracy of ±1.5%. The device operates within a temperature range of -40°C to +85°C and features a maximum temperature coefficient of 138 ppm/°C. It supports a maximum cathode current of 15 mA and a minimum cathode current of 80 µA. The component is housed in a 5-pin SOT-23 package and complies with RoHS standards.

Feature Summary

• Adjustable output voltage capability spanning from 1.24 V to 6 V for flexible circuit design
• Precision regulation performance with ±1.5% initial accuracy tolerance
• Low minimum operating current requirement of 80 µA for efficient standby modes

Applications

• Battery-powered equipment requiring precise voltage monitoring
• Portable devices utilizing low-voltage power supplies
• General-purpose voltage reference circuits in consumer electronics

Procurement Notes

Verify the specific suffix 'TG4' indicates lead-free and RoHS compliance as per manufacturer documentation. Confirm the package designation matches the required SOT-23 footprint for PCB layout compatibility. Ensure the operating temperature range meets the environmental specifications of the target application. Cross-reference the datasheet revision to confirm electrical characteristics remain consistent with current production standards.

Selection Notes

Select this component when a low-cost, high-precision voltage reference is needed for low-voltage applications. The ±1.5% accuracy offers a balance between cost and performance compared to tighter tolerance variants. Consider the 15 mA current limit when designing feedback networks to ensure stable operation under varying load conditions. Verify that the 6 V maximum output voltage aligns with the system's supply rails.

Part Context

This part belongs to the TLV431 family of adjustable shunt regulators designed for low-voltage systems. It serves as a drop-in replacement for standard TL431 devices in applications where lower input voltages are utilized. The family is widely used in power management circuits due to its compact size and reliable performance in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include the TLV431CDBVT and TLV431CDBVTE4. These alternatives share identical electrical specifications and pin configurations. Verify package compatibility and temperature ratings before substitution.
