Overview
The TL431CLPX is an adjustable shunt voltage reference integrated circuit manufactured by onsemi. It provides a precise output voltage ranging from 2.495V to 36V with a typical dynamic impedance of 0.22 Ω. The device supports an operating current range of 1.0 mA to 100 mA and features a tolerance of ±2.2%. Packaged in a TO-92-3 configuration, it serves as a stable reference element for power supply regulation and monitoring applications.
Feature Summary
- Adjustable output voltage capability spanning 2.495V to 36V
- Low dynamic impedance for stable reference performance
- Wide operating current range supporting diverse load conditions
Applications
- Secondary regulation in switch-mode power supplies
- Precision voltage references in adapter circuits
- Voltage monitoring and control loops
Procurement Notes
Verify the specific suffix CLPX against the official onsemi datasheet to confirm package type and temperature grade compatibility. Ensure the ordering part number matches the required tolerance and operational specifications for your design. Cross-reference manufacturer documentation to validate RoHS compliance status and material composition declarations prior to procurement.
Selection Notes
Select this component when an adjustable precision reference is required within a TO-92-3 form factor. Consider the 1.0 mA to 100 mA operating range to ensure adequate biasing for your application. Evaluate the ±2.2% tolerance against system accuracy requirements. Confirm thermal management needs align with the package capabilities for continuous operation.
Part Context
This device belongs to the TL431 family of programmable precision shunt voltage references widely used in power management. The CLPX variant specifically denotes the TO-92-3 through-hole package option. These components are standard solutions for feedback loop stabilization in linear and switching regulators, offering a cost-effective alternative to fixed-bandgap references.
Replacement Considerations
Compatible substitutes include the TL431AIDR and NCP431A series from onsemi. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure the replacement part meets the same voltage and current specifications for direct integration.
