Overview
The TLVH431IDBVTG4 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 supports an adjustable output voltage from 1.24V to 18V with a maximum series reference input voltage of 20V. It utilizes a SOT-23-5 surface-mount package and offers a maximum cathode current of 80mA with a minimum operating current of 80uA.
Feature Summary
- Provides high-precision voltage regulation with 0.5% initial accuracy for stable reference applications.
- Supports wide adjustable output voltage range from 1.24V up to 18V using external resistors.
- Operates efficiently with low minimum cathode current requirements suitable for battery-powered systems.
Applications
- Precision voltage references in portable electronic devices
- Feedback elements in switching power supplies
- Battery management system monitoring circuits
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the SOT-23-5 package outline matches your PCB footprint design constraints. Ensure the 0.5% accuracy grade meets your circuit tolerance requirements before finalizing component selection.
Selection Notes
Select this component when precise low-voltage regulation is required in space-constrained designs. The SOT-23-5 package offers a compact solution compared to larger alternatives. Consider the 80uA minimum current requirement to ensure stability in low-load conditions, distinguishing it from higher-current shunt regulators.
Part Context
This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. It serves as a direct replacement for standard TL431 variants in low-voltage applications, offering improved performance characteristics such as lower minimum operating current and tighter accuracy specifications within the same functional category.
Replacement Considerations
Compatible substitutes include TLVH431IDBVTE4 and other members of the TLVH431 family with matching accuracy grades and package types. Verify pinout compatibility and thermal characteristics when substituting with similar shunt regulators from different manufacturers.
