Overview
The TL431BCDR2G is an adjustable shunt voltage reference IC manufactured by onsemi, belonging to the TL431 series. It operates within a reference voltage range of 2.5 V to 36 V and features an initial accuracy of ±0.4%. The device supports a maximum cathode current of 100 mA and has a maximum input voltage rating of 37 V. It utilizes an SOIC-8 surface-mount package with dimensions of 5 mm x 4 mm x 1.5 mm. The component functions across a temperature range of 0°C to 70°C, exhibits a temperature coefficient of 50 ppm/°C, and meets AEC-Q100 automotive standards.
Feature Summary
- Provides programmable output voltage ranging from 2.5 V to 36 V via external resistor divider
- Delivers high precision with ±0.4% initial accuracy for stable reference applications
- Supports up to 100 mA cathode current for driving feedback loops or loads
- Complies with AEC-Q100 automotive qualification standards for reliability
Applications
- Precision power supply regulation circuits
- Programmable output controllers in switching regulators
- Voltage monitoring and protection circuits
- Linear regulator error amplifiers
Procurement Notes
Verify the specific suffix DR2G confirms the SOIC-8 tape-and-reel packaging configuration. Confirm the B grade designation aligns with the required ±0.4% accuracy tolerance for the design. Ensure the operating environment remains within the specified 0°C to 70°C thermal range. Validate that the 37 V maximum input voltage exceeds the circuit's peak supply conditions. Check for any recent product change notices affecting pinout or material composition.
Selection Notes
Select this component when a high-precision adjustable reference is required in a compact surface-mount format. The ±0.4% accuracy makes it suitable for applications demanding tight voltage tolerances compared to standard grades. The AEC-Q100 certification allows integration into automotive systems without additional qualification steps. Consider the 100 mA current capability for direct drive requirements without external buffering.
