TL431BILPE3

Overview

The TL431BILPE3 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates with an output voltage range of 2.495 V to 36 V and supports a maximum cathode current of 100 mA. The device features an initial accuracy of ±0.5% and a maximum temperature coefficient of 92 ppm/°C. It is housed in a 3-pin TO-92 through-hole package. The component functions within a temperature range of -40°C to +85°C and complies with RoHS standards.

Feature Summary

• Provides precise adjustable voltage reference functionality via a shunt regulation topology.
• Delivers high initial accuracy of ±0.5% for stable reference applications.
• Operates reliably across an extended industrial temperature range.

Applications

• Precision voltage references in power supply circuits
• Programmable linear regulators
• Voltage monitoring and control systems

Procurement Notes

Verify the specific suffix 'E3' indicates lead-free compliance and RoHS status. Confirm the package type is TO-92-3 through-hole. Check current part status as some variants may be obsolete. Ensure the operating temperature range meets system requirements. Validate pinout compatibility during integration.

Selection Notes

Select this component when ±0.5% accuracy is required for voltage referencing. Choose the TO-92 package for through-hole assembly needs. Consider the 100 mA current limit for load requirements. Verify thermal performance within the specified -40°C to +85°C range. Compare against lower accuracy grades if cost is a primary constraint.

Part Context

This part belongs to the TL431 family of programmable shunt regulators. It serves as a versatile reference element in analog and mixed-signal circuits.
