TLVH432BIPK

Overview

The TLVH432BIPK is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 20 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of ±0.5% and a temperature coefficient of 138 ppm/°C. It supports a maximum cathode current of 80 mA with a minimum operating current of 80 µA. The component is housed in a SOT-89-3 surface-mount package and functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

• Adjustable output voltage capability spanning from 1.24 V to 18 V for flexible circuit design
• High initial accuracy of ±0.5% ensures precise voltage regulation performance
• Wide operating temperature range supporting operation from -40°C to +125°C

Applications

• Precision power management systems requiring stable reference voltages
• Battery-powered equipment utilizing low-voltage shunt regulation
• Industrial control circuits demanding high accuracy over wide temperature ranges

Procurement Notes

Verify component authenticity through authorized channels as the TLVH432BIPK is listed as obsolete. Confirm availability of qualified substitutes such as the TLVH432BCPK before finalizing procurement plans. Ensure all sourcing partners provide valid traceability documentation to mitigate risks associated with discontinued part numbers.

Selection Notes

Select this component when ±0.5% initial accuracy is required for shunt regulation applications. The SOT-89-3 package suits designs needing compact surface-mount solutions. Consider the 80 mA cathode current limit for load requirements. Evaluate thermal performance within the specified -40°C to +125°C operational envelope during system integration.

Part Context

The TLVH432BIPK belongs to the TLVH432 family of low-voltage adjustable precision shunt regulators. This series offers improved accuracy compared to standard zener diodes. The B suffix denotes the ±0.5% accuracy grade, distinguishing it from other variants like the A or Q grades. It serves as a direct replacement for many legacy adjustable references in modern power management designs.

Replacement Considerations

The TLVH432BCPK is identified as an available substitute for the obsolete TLVH432BIPK. Verify pinout compatibility and electrical specifications before implementation.
