TL431BILPRE3

Overview

The TL431BILPRE3 is a precision adjustable shunt voltage reference manufactured by Texas Instruments. It operates within an output voltage range of 2.495 V to 36 V and features an initial accuracy of ±0.5%. The device supports a maximum cathode current of 100 mA with a minimum operating current of 700 µA. It utilizes a TO-92-3 through-hole package and functions across a temperature range of -40°C to +85°C. The component has a maximum input voltage rating of 36 V and a temperature coefficient of 92 ppm/°C.

Feature Summary

Provides high-precision voltage regulation with ±0.5% initial accuracy for stable reference applications
Features sharp turn-on characteristics suitable for feedback control in switching power supplies
Operates as a programmable shunt regulator with wide adjustable output voltage capability

Applications

Feedback control loops in switching power supplies
Precision voltage references in portable equipment
On-line differential amplifiers
Power supply output voltage regulation

Procurement Notes

Verify the specific suffix 'PRE3' confirms RoHS compliance and lead-free manufacturing status, as this indicates environmental adherence. Confirm the package type matches the required TO-92-3 through-hole footprint for PCB integration. Check the latest manufacturer notices regarding end-of-life status or material changes to ensure long-term availability for production cycles.

Selection Notes

Select this component when a tight tolerance of ±0.5% is required compared to standard 2% or 1% variants. Ensure the circuit design accommodates the 700 µA minimum cathode current requirement for proper regulation. Verify that the thermal environment remains within the specified -40°C to +85°C operational range for consistent performance.

Part Context

This part belongs to the TL431 family of programmable shunt regulators, originally released in 1978 as an improvement over the TL430. The TL431 series is widely used in power management ICs for its stability and accuracy. The 'B' designation typically denotes the tighter ±0.5% accuracy grade within the product line.
