TL432BIPK

Overview

The TL432BIPK is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a cathode voltage range of 2.495 V to 36 V and supports a maximum cathode current of 100 mA. The device features an initial accuracy tolerance of ±0.5% and a temperature coefficient of 92 PPM/°C. It functions reliably across an operating temperature range of -40°C to +125°C. The component is housed in a surface-mount SOT-89-3 package.

Feature Summary

• Provides high-precision voltage reference with ±0.5% initial accuracy
• Supports wide operating temperature range from -40°C to +125°C
• Features low temperature coefficient for stable performance

Applications

• Precision power supply regulation
• Voltage reference circuits
• Portable equipment power management

Procurement Notes

Verify the specific suffix 'BIPK' corresponds to the SOT-89-3 package and ±0.5% tolerance grade as documented. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering information matches the manufacturer's latest datasheet specifications before finalizing procurement.

Selection Notes

Select this component when a compact SOT-89-3 footprint is required alongside high precision. The ±0.5% tolerance suits applications demanding tighter accuracy than standard references. Consider the 125°C maximum junction temperature for thermal design in enclosed environments compared to lower-rated alternatives.

Part Context

This part belongs to the TL432 family of adjustable shunt regulators, designed as a drop-in replacement for Zener diodes in many applications. It offers superior performance characteristics including lower dynamic impedance and better temperature stability compared to traditional discrete Zener solutions.
