Overview
The TLVH431AIDBVT is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 1.24 V to 18 V and features an initial accuracy of 0.5%. The device supports a maximum cathode current of 80 mA with a minimum operating current of 80 µA. It has a maximum supply voltage of 20 V and a temperature coefficient of 138 ppm/°C. The component functions across an extended temperature range from -40°C to +125°C and is housed in a SOT-23-5 surface-mount package.
Feature Summary
- Provides adjustable output voltage capability via external resistor divider
- Ensures high precision with 0.5% initial accuracy specification
- Supports wide operating current range for flexible circuit design
Applications
- Battery chargers
- Switch mode power supplies
- Data acquisition systems
Procurement Notes
Verify the specific suffix 'DBVT' corresponds to the SOT-23-5 package and cut-tape reel format. Confirm RoHS compliance status through official documentation. Ensure the 0.5% accuracy grade matches application requirements. Check for any automotive qualification markings if used in vehicle electronics. Validate lead-free manufacturing standards against project specifications.
Selection Notes
Select this component when low-voltage operation and high precision are required. The wide current range allows compatibility with various load conditions. The small SOT-23-5 package suits space-constrained designs. Consider the temperature stability for environments with significant thermal variations. Compare against fixed reference options if voltage flexibility is not needed.
Part Context
This part belongs to the TLVH431 series of low-voltage adjustable shunt regulators. It serves as a three-terminal voltage reference alternative to standard Zener diodes. The series offers improved performance over traditional references in terms of temperature stability and dynamic impedance. It is designed for applications requiring precise voltage regulation in compact form factors.
Replacement Considerations
Check for direct substitutes like TLVH431AIDBVR or TLVH431AIDBVTG4. Verify pinout compatibility before swapping packages. Ensure accuracy grades match if tighter tolerances are required. Confirm operating temperature ranges align with environmental conditions.
