Overview
The TL431BCLPR is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495V to 36V and features an initial accuracy of 0.5%. The device supports a maximum cathode current of 100mA and maintains a temperature coefficient of 92 PPM/C. It functions in an industrial temperature range from -40°C to +85°C. The component utilizes a TO-92-3 through-hole package, ensuring compatibility with standard PCB layouts for power management applications requiring stable reference voltages.
Feature Summary
- Provides high-precision adjustable voltage regulation with 0.5% initial accuracy
- Operates as a shunt regulator with wide input voltage capability up to 36V
- Designed for robust performance across extended industrial temperature ranges
Applications
- Precision voltage references in power supply circuits
- Programmable output regulators
- Voltage monitoring and control systems
Procurement Notes
Verify the specific suffix CLPR against official datasheets to confirm package type and accuracy grade. Confirm RoHS compliance status and check for recent Product Change Notifications or End-of-Life notices directly from Texas Instruments documentation before finalizing procurement decisions.
Selection Notes
Select this component when 0.5% accuracy is required for shunt regulation applications. Ensure the operating environment stays within the specified -40°C to +85°C range. Verify that the TO-92-3 through-hole package aligns with the target PCB design constraints and thermal requirements.
Part Context
This part belongs to the TL431 family of programmable shunt regulators. These devices serve as versatile alternatives to Zener diodes, offering superior stability and adjustability. The TL431 series is widely utilized in feedback loops for switching power supplies and linear regulators to maintain precise output voltage levels under varying load conditions.
Replacement Considerations
Check for direct equivalents such as TL431ACLP or TL431AILP if different accuracy grades are acceptable. Verify pinout compatibility and thermal characteristics before substituting with other manufacturers' parts.
