Overview
The TL432AQPK is an adjustable precision shunt regulator manufactured by Texas Instruments, housed in a SOT-89-3 surface-mount package. It provides an adjustable output voltage ranging from the internal reference of 1.24V up to 36V. The device features an initial accuracy of 1% and operates within a temperature range of -40°C to +125°C. Key electrical specifications include a maximum series input voltage of 36V, a maximum shunt current of 100mA, and a minimum shunt current of 600µA. The temperature coefficient is specified at 92 PPM/°C.
Feature Summary
- Provides precise adjustable voltage regulation with 1% initial accuracy
- Capable of sinking cathode currents from 600µA to 100mA
- Operates reliably across extended industrial temperature ranges
Applications
- Precision voltage references in power supply circuits
- Adjustable linear and switching power supplies
- Battery charging systems requiring stable reference voltages
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level handling requirements prior to assembly. Check for obsolescence notices as availability may be limited. Ensure packaging specifications match production line requirements for surface mount technology integration.
Selection Notes
Select this component when high precision and wide operating temperature range are required. The SOT-89-3 package offers compact surface-mount integration suitable for space-constrained designs. Consider the 1% tolerance and low temperature coefficient for applications demanding stable reference performance under varying thermal conditions.
Part Context
This part belongs to the TL432 family of adjustable precision shunt regulators from Texas Instruments. It serves as a three-terminal voltage reference alternative to fixed zener diodes, offering superior stability and adjustability. The device integrates a bandgap reference and error amplifier to maintain precise output regulation across the specified current and voltage ranges.
Replacement Considerations
Compatible substitutes include TL432AIPK and TL432IPK from Texas Instruments, which share similar pinouts and functional characteristics. Verify specific tolerance grades and temperature ratings when substituting to ensure design requirements are met.
