Overview
The TLV431BIDBZTG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 6 V and supports a maximum cathode current of 15 mA. The device features an initial accuracy of 0.5% and a maximum temperature coefficient of 138 ppm/°C. It functions with a maximum input voltage of 7 V and is rated for operation between -40 °C and 85 °C. The component is housed in a surface-mount SOT-23 package with three pins and is supplied in tape and reel packaging.
Feature Summary
- Provides adjustable reference voltage functionality within the specified low-voltage range
- Delivers high initial accuracy for precise regulation applications
- Operates reliably across standard industrial temperature ranges
Applications
- Low-voltage power supply regulation
- Precision voltage references in portable electronics
- Feedback control loops in battery-powered devices
Procurement Notes
Verify the specific suffix DBZT indicates the SOT-23-3 tape and reel configuration. Confirm the Q1 or B grade designation matches the required 0.5% accuracy specification for your design. Ensure the operating environment stays within the -40 °C to 85 °C thermal limits defined for this variant. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.
Selection Notes
Select this component when a compact, low-cost adjustable reference is needed for voltages up to 6 V. It is suitable for designs requiring tighter tolerance than standard TL431 variants but do not exceed the 15 mA current limit. Consider the SOT-23 footprint constraints and the specific temperature coefficient requirements of the application circuit.
Part Context
This part belongs to the TLV431 family of low-voltage adjustable shunt regulators from Texas Instruments. It serves as a modern alternative to higher voltage counterparts, optimized for single-cell battery systems and low-voltage logic interfaces. The IDBZTG4 suffix denotes the specific package type, accuracy grade, and reel packaging format.
Replacement Considerations
Direct substitutes include other TLV431 variants with matching SOT-23-3 packages and 0.5% accuracy grades, such as TLV431AIDBZTG4, provided the 1% accuracy difference is acceptable. Verify that any replacement maintains the same 15 mA current capability and 7 V maximum input voltage rating.
