TL432ACPK

Overview

The TL432ACPK is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input voltage range of 2.5V to 36V and provides an adjustable output voltage from 1.24V to 18V. The device features a typical reference voltage accuracy of ±1% and supports a maximum cathode current of 100mA. It is housed in a 3-pin SOT-89 surface-mount package and is rated for operation across an extended temperature range of -40°C to 125°C.

Feature Summary

Provides precise adjustable voltage regulation via external resistor divider
Operates with low minimum cathode current requirements
Designed for high stability and low noise performance

Applications

Portable equipment power supplies
DC-to-DC converter feedback loops
Battery chargers
Power supply monitoring circuits

Procurement Notes

Verify the specific suffix 'ACPK' against the official Texas Instruments datasheet to confirm the exact tolerance grade, temperature range, and packaging configuration. Ensure the ordering part number matches the required specifications for your design implementation.

Selection Notes

Select this component when a compact, low-cost adjustable reference is needed for space-constrained designs. Consider the SOT-89 package constraints and thermal dissipation capabilities relative to the expected load current and ambient operating conditions.

Part Context

This device belongs to the TL432 family of programmable shunt regulators. It serves as a cost-effective alternative to Zener diodes, offering superior accuracy and temperature stability. The family includes variants with different tolerances and packages to suit various industrial and consumer applications.

Replacement Considerations

Compatible replacements include other TL432 variants such as TL432AIPK or TL432QPK, provided they match the required electrical characteristics and pinout compatibility.
