Overview
The TL1431MDREPG4 is a precision programmable shunt reference manufactured by Texas Instruments. It operates within an output 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 withstands input voltages up to 37 V. It functions reliably across a temperature range of -40°C to +125°C with a temperature coefficient of 114 PPM/°C. The component is housed in an 8-pin SOIC package.
Feature Summary
- Provides precise adjustable voltage referencing for circuit regulation
- Ensures stable operation across extended industrial temperature ranges
- Supports high cathode current capabilities for robust load handling
Applications
- Battery-powered equipment requiring accurate voltage monitoring
- DC-to-DC converter feedback loops for output regulation
- Portable instrumentation needing stable reference sources
Procurement Notes
Verify the specific suffix 'EPG4' against official Texas Instruments documentation to confirm environmental compliance and lead-free status. Ensure the SOIC-8 package matches your PCB footprint requirements. Confirm that the 0.4% initial accuracy meets your design tolerance specifications before finalizing procurement.
Selection Notes
Select this component when a low-cost, high-accuracy shunt reference is required for linear regulator applications. The wide operating voltage range allows flexibility in designing feedback networks. Consider the thermal performance and package size constraints relative to other available Texas Instruments programmable references.
Part Context
This part belongs to the TL1431 family of precision programmable references. It serves as a direct replacement for standard TL431 devices in many designs, offering improved accuracy and stability. The family is widely used in power supply designs where reliable voltage regulation is critical for system performance.
Replacement Considerations
Check for compatible equivalents such as the TL1431QDRG4Q1 or generic TL431 variants. Verify pinout compatibility and electrical parameter overlaps to ensure seamless integration without redesigning the surrounding circuitry.
