Overview
The TLV431AIDBVRG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It provides an initial accuracy of 1% and operates within a temperature range of -40°C to +85°C. The device features a maximum output voltage of 6 V, with an adjustable reference input voltage maximum of 1.258 V. It supports a maximum shunt current of 15 mA and a minimum shunt current of 80 uA. The unit utilizes a SOT-23-5 package.
Feature Summary
- Adjustable precision shunt regulation for low-voltage applications
- High initial accuracy for stable reference performance
- Compact surface-mount packaging for space-constrained designs
Applications
- Low-voltage power supply feedback loops
- Portable equipment voltage references
- Battery-powered system monitoring
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the SOT-23-5 package variant matches the design footprint requirements. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the datasheet revision to confirm electrical characteristics remain consistent with the specified parameters.
Selection Notes
Select this component when a precise, low-cost voltage reference is required in a small form factor. The 1% accuracy suits general-purpose applications where tighter tolerances are unnecessary. Consider the 15 mA current limit for load driving capabilities. Evaluate the thermal performance within the specified operating temperature range during circuit design.
Part Context
This part belongs to the TLV431 family of adjustable shunt regulators from Texas Instruments. It serves as a low-voltage alternative to standard Zener diodes, offering superior stability and adjustability. The device integrates a bandgap reference and error amplifier to maintain precise output voltages across varying load and temperature conditions.
Replacement Considerations
Check for direct pin-compatible alternatives within the same family, such as TLV431AIDBVT or TLV431AIDBZRG4, ensuring identical accuracy and package dimensions. Verify that any substitute maintains the same electrical specifications and regulatory compliance status.
