Overview
The TLV431AIDBVT 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 features an initial accuracy of 1%. The device supports a maximum cathode current of 15 mA and has a maximum reference input voltage of 7 V. It exhibits a temperature coefficient of 138 ppm/°C and functions across a temperature range from -40°C to +125°C. The component is housed in a SOT-23-5 surface-mount package.
Feature Summary
- Provides adjustable precision voltage regulation with high initial accuracy for stable reference applications.
- Operates at low voltages, enabling efficient power management in battery-powered or low-voltage systems.
- Designed for compact integration using a small five-pin surface-mount package.
Applications
- Precision voltage references in portable electronic devices
- Feedback control loops in switching power supplies
- Battery-operated equipment requiring stable reference voltages
Procurement Notes
Verify the specific suffix DBVT confirms the SOT-23-5 package and cut-tape reel format upon ordering. Confirm that the 'A' grade designation aligns with the required 1% initial accuracy specifications for your design. Ensure compatibility with the specified operating temperature range of -40°C to +125°C. Cross-reference the manufacturer part number against official datasheets to confirm RoHS compliance status.
Selection Notes
Select this component when a low-voltage adjustable shunt regulator with 1% accuracy is required in a compact SOT-23-5 footprint. It is suitable for designs needing operation up to 7 V input with a maximum cathode current of 15 mA. Consider the 138 ppm/°C temperature coefficient for thermal stability requirements. Verify that the extended industrial temperature range meets environmental constraints.
Part Context
This device belongs to the TLV431A series of low-voltage adjustable precision shunt regulators from Texas Instruments. It serves as a direct replacement for traditional Zener diodes in feedback circuits. The family offers various accuracy grades and package options to suit different space and precision requirements in power management applications.
Replacement Considerations
Check for equivalent parts such as TLV431AIDBVR for alternative packaging formats. Verify if higher accuracy variants like the TLV431BIDBVT are needed for tighter tolerance requirements. Ensure pinout compatibility when substituting with other manufacturers' adjustable shunt regulators.
