Overview
The TLV431ACDBVRG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It provides an adjustable output voltage ranging from 1.24 V to 18 V with an initial accuracy of ±1%. The device operates with a maximum cathode current of 100 mA and supports input voltages up to 36 V. It is housed in a compact SOT-23-5 surface-mount package, designed for space-constrained applications requiring stable voltage reference performance.
Feature Summary
- Adjustable output voltage range from 1.24 V to 18 V
- High initial accuracy of ±1% across operating temperature range
- Low cathode current operation down to 80 µA
- Compact SOT-23-5 surface-mount package
Applications
- Portable equipment power management
- Battery-powered systems
- DC/DC converter feedback loops
- Linear regulator references
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm RoHS compliance status and lead-free characteristics. Ensure the ordering part number matches the exact package type and tape-and-reel specifications required for your assembly process. Cross-reference with the latest datasheet revision to confirm active status and any potential obsolescence notices.
Selection Notes
Select this component when a low-voltage, high-precision adjustable reference is needed in a small footprint. The ±1% accuracy makes it suitable for applications demanding tight voltage regulation without external trimming. Consider the 100 mA cathode current capability for driving moderate loads or feedback networks in switching regulators.
Part Context
This part belongs to the TLV431 family of low-voltage adjustable shunt regulators. It serves as a drop-in replacement for standard TL431 devices in low-voltage applications, offering improved performance at lower supply voltages. The family is widely used in consumer electronics and industrial control systems where space and precision are critical constraints.
Replacement Considerations
Direct substitutes include the TLV431ACDBVT and TLV431ACDBVTE4. Verify pinout compatibility and electrical parameter equivalence before substitution. Check manufacturer announcements for any recommended upgrades or end-of-life notifications affecting the G4 suffix variant.
