Overview
The TL431IDBVR is an adjustable precision shunt regulator manufactured by Texas Instruments, housed in a SOT-23-5 surface-mount package. It provides a reference voltage range from 2.495 V to 36 V with an initial accuracy of ±2.2%. The device supports a maximum cathode current of 100 mA and operates within a temperature range of -40°C to 85°C.
Feature Summary
- Adjustable output voltage capability spanning from 2.495 V up to 36 V for flexible circuit design.
- High initial accuracy specification ensuring precise voltage regulation performance.
- Robust thermal stability maintained across extended industrial operating temperature ranges.
Applications
- Precision voltage references in power supply circuits
- Programmable linear regulators requiring stable reference points
- Voltage monitoring systems needing accurate threshold detection
Procurement Notes
Verify the specific suffix 'DBVR' corresponds to the SOT-23-5 package and tape-and-reel packaging configuration. Confirm that the ±2.2% accuracy grade meets the system requirements, as other grades like 'A' or 'B' offer tighter tolerances. Ensure the operating environment remains within the specified -40°C to 85°C range for optimal performance.
Selection Notes
Select this component when a cost-effective, high-current shunt regulator is required for general-purpose voltage referencing. The SOT-23-5 package offers space efficiency compared to larger through-hole options. Consider higher accuracy variants if the application demands tighter tolerance than the standard ±2.2% specification allows.
Part Context
This part belongs to the TL431 family of programmable zener diodes, widely used as low-cost alternatives to traditional bandgap references. The TL431 series is known for its versatility in feedback loops and comparator applications, providing a reliable solution for voltage regulation tasks in various electronic designs.
Replacement Considerations
TL431AIDBVR (±1% accuracy), TL431BIDBVR (±0.5% accuracy). These variants share the same package and pinout but offer improved initial accuracy specifications.
