Overview
The TL431ACLPREG is a three-terminal programmable shunt regulator diode from onsemi, part of the TL431A series. It operates as a low temperature coefficient zener, programmable from Vref to 36 V using two external resistors. The device features a reference voltage tolerance of ±1% and an equivalent full-range temperature coefficient of 50 ppm/°C typical. It supports a cathode current range of 1.0 mA to 100 mA with a typical dynamic impedance of 0.22 Ω. Designed for surface mount applications, it utilizes the TO-92 (TO-226) LP suffix package.
Feature Summary
- Programmable output voltage adjustable from Vref up to 36 V via external resistors
- Temperature compensated operation across the rated ambient temperature range
- Low dynamic output impedance for stable regulation performance
- RoHS compliant and lead-free construction
Applications
- Digital voltmeters
- Power supplies
- Op amp circuitry
- Shunt regulators
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and shipping configuration. Confirm that the component meets the required operating temperature range specifications for the intended application environment before finalizing procurement decisions.
Selection Notes
Select this component when a precise, adjustable voltage reference is required in a compact form factor. Ensure the design accommodates the specified cathode current limits and load capacitance requirements to maintain stability within the recommended operating conditions defined in the datasheet.
Part Context
This device belongs to the TL431 family of programmable precision references manufactured by onsemi. It serves as a direct replacement for standard Zener diodes in various analog and digital circuits, offering superior accuracy and temperature stability compared to discrete Zener solutions.
Replacement Considerations
Consult the official datasheet discontinuation notices for legacy variants. Verify pinout compatibility and thermal characteristics when substituting with other manufacturers' programmable shunt regulators.
