Overview
The TL431IDBVTG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 2.495 V to 36 V and provides an initial accuracy of ±2%. The device supports a maximum cathode current of 100 mA and functions across an extended temperature range from -40 °C to +85 °C. It is housed in a compact SOT-23-5 surface-mount package, designed for applications requiring stable voltage reference performance in space-constrained environments.
Feature Summary
- Provides precise voltage regulation with high initial accuracy
- Supports wide output voltage adjustability
- Operates reliably across extended industrial temperature ranges
Applications
- Precision voltage references in power supply circuits
- Feedback control loops in switching regulators
- Portable equipment requiring compact voltage regulation
Procurement Notes
Verify the complete part number including the G4 suffix to ensure compliance with specific environmental standards. Confirm the package type matches the design requirements. Check for any recent product change notifications that may affect assembly or sourcing. Ensure the supplier provides valid traceability documentation for quality assurance purposes.
Selection Notes
Select this component when a small footprint is required alongside high precision. Compare the ±2% accuracy against tighter tolerance options if higher precision is needed. Consider the operating temperature range relative to the application environment. Evaluate the SOT-23-5 package dimensions against available board space constraints.
Part Context
This device belongs to the TL431 family of adjustable shunt regulators, widely used as voltage references and error amplifiers. The ID variant specifies the accuracy grade, while the DBVT package code indicates the specific surface-mount housing. The G4 suffix denotes lead-free construction compliant with RoHS directives.
Replacement Considerations
Direct replacements include TL431IDBVR and TL431IDBVRE4. Verify pin compatibility and electrical specifications before substitution. Ensure the alternative part meets the same accuracy and temperature requirements.
