TL431ALP-AP

Overview

The TL431ALP-AP is a programmable shunt voltage reference IC manufactured by Micro Commercial Components. It operates within a supply voltage range of up to 36 V and provides a nominal output voltage of 2.5 V. The device supports a maximum output current of 100 mA. It is housed in a TO-92 through-hole package and functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• Programmable precision regulation with adjustable output voltage capabilities
• Monolithic integrated circuit design for stable thermal performance
• Three-terminal configuration simplifying circuit integration

Applications

• Precision voltage references in power supply circuits
• On-line isolation amplifiers
• Voltage regulators requiring high stability

Procurement Notes

Verify the specific suffix AP against the manufacturer's current product status, as availability may vary. Confirm that the TO-92 package and 0-70°C operating range align with your system requirements. Ensure compatibility with existing PCB footprints and thermal management strategies before finalizing procurement decisions.

Selection Notes

Select this component when a low-cost, programmable shunt regulator is required for general-purpose applications. The TO-92 package suits through-hole assembly processes. Consider the 100 mA sink current limit and 36 V maximum voltage rating to ensure safe operation within the intended circuit parameters without exceeding absolute maximum ratings.

Part Context

This part belongs to the TL431 family of programmable shunt regulators, widely used as voltage references. MCC produces variants with different tolerance grades and packaging options. The TL431ALP-AP specifically denotes a standard tolerance version in a TO-92 case, serving as a fundamental building block for feedback loops in switching and linear power supplies.

Replacement Considerations

Compatible substitutes include the TL431A from other manufacturers such as Texas Instruments or STMicroelectronics, provided they meet the same electrical specifications and pinout compatibility. Verify that alternative parts support the TO-92 package and similar operating temperature ranges.
