Overview
The TLVH431CDBZRG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 18 V and supports a maximum cathode current of 70 mA. The device features an initial accuracy of 1% and functions across an extended temperature range from -40 °C to +125 °C. Packaged in a compact SC-70-6 (SOT-363) surface-mount format, it is designed for applications requiring precise voltage referencing in space-constrained environments.
Feature Summary
- Provides stable reference voltage with high initial accuracy
- Operates efficiently at low voltages
- Suitable for harsh thermal environments
Applications
- Battery-powered portable devices
- Low-voltage power supply regulation
- Precision voltage monitoring circuits
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the SC-70-6 package variant matches design constraints. Ensure sourcing channels provide genuine Texas Instruments components to avoid counterfeit risks. Check for automotive or industrial qualification requirements if applicable to the end-use environment.
Selection Notes
Select this component when a low-voltage, high-accuracy reference is required in a small footprint. Compare against standard TLV431 series for improved low-voltage performance. Consider the 70 mA current limit for load driving capabilities. Evaluate thermal management needs given the wide operating temperature range and surface-mount packaging limitations.
Part Context
This part belongs to the TLVH431 family of low-voltage shunt regulators. It serves as a drop-in replacement for traditional TL431 devices in low-voltage applications where lower minimum operating voltage is critical. The family offers improved performance characteristics compared to older generations, specifically targeting modern portable electronics and battery-operated systems.
Replacement Considerations
Direct substitutes include other TLVH431 variants with compatible packages. Verify pinout compatibility before substitution. Cross-reference with TLV431 series for general-purpose replacements if voltage ranges align.
