TL431ILPR

Overview

The TL431ILPR is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495V to 36V and features a ±1% initial accuracy tolerance. The device supports a maximum cathode current of 100mA and maintains a typical temperature coefficient of 92 ppm/°C. Designed for through-hole mounting, it utilizes the TO-92-3 (TO-226AA) package. The component functions effectively across a wide ambient temperature range from -40°C to 85°C.

Feature Summary

Provides precise programmable reference voltage functionality with high stability
Operates as an adjustable shunt regulator suitable for feedback control loops
Delivers robust performance with low dynamic impedance characteristics

Applications

Voltage regulation in power supply circuits
Programmable linear regulators
Feedback control systems requiring precise voltage references
Battery management applications

Procurement Notes

Verify the specific suffix 'ILP' corresponds to the required ±1% accuracy grade and TO-92 package configuration. Confirm that the 'R' suffix indicates tape-and-reel packaging if automated assembly is intended. Ensure the operating temperature range meets the environmental requirements of the target application before finalizing procurement.

Selection Notes

Select this component when a low-cost, high-accuracy adjustable reference is needed for shunt regulation. The TO-92 package offers a compact solution for through-hole designs. Consider the 100mA current capability for load driving requirements. Verify thermal management needs against the specified operating temperature limits.

Part Context

This part belongs to the TL431 family of programmable references, widely used in industrial and consumer electronics. It serves as a cost-effective alternative to fixed voltage references, offering flexibility in circuit design. The series is known for its reliability and widespread adoption in power management applications.
