TL431BU-TP

Overview

The TL431BU-TP is a programmable precision shunt voltage regulator manufactured by Micro Commercial Components (MCC). It operates within a cathode voltage range of 2.5V to 36V and provides an adjustable reference output. The device features a typical dynamic impedance of 0.22Ω and maintains a low temperature coefficient of 50ppm/°C over the commercial operating temperature range of 0°C to 70°C. It supports a cathode current range from 1mA to 100mA and is housed in a surface-mount SOT-23 package.

Feature Summary

Programmable output voltage ranging from 2.5V to 36V
Low dynamic impedance for stable regulation
Surface-mount SOT-23 packaging for compact designs

Applications

Precision voltage references
Linear and switching power supply regulation
Portable equipment power management

Procurement Notes

Verify component authenticity through authorized MCC distributors or certified partners. Confirm the specific suffix matches the required tolerance and temperature grade. Request official datasheets and test reports to ensure compliance with specified electrical parameters before integration into production systems.

Selection Notes

Select this component when a compact, programmable shunt regulator is required for commercial temperature applications. Ensure the design accommodates the 0°C to 70°C operating range and that the load current remains within the 1mA to 100mA specification. Verify that the SOT-23 footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the TL431 family of programmable zener diodes, widely used as voltage references and error amplifiers in power conversion circuits. The BU-TP suffix indicates the specific package type and manufacturing lot tracking for Micro Commercial Components. It serves as a direct functional replacement for industry-standard TL431 devices in similar form factors.

Replacement Considerations

Compatible substitutes include the TL431AIDBZR and TL431DBZ, provided they match the SOT-23 package and electrical specifications. Verify pinout compatibility and thermal performance characteristics before substitution to ensure circuit stability.
