Overview
The TL432AQDBZTG4 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495V to 36V and features an initial accuracy of 1%. The device supports a maximum cathode current of 100mA with a minimum operating current of 600µA. It functions reliably across a temperature range of -40°C to +125°C. The component utilizes a SOT-23-3 surface-mount package and complies with RoHS standards.
Feature Summary
- Provides precise programmable reference voltage functionality
- Supports wide input voltage operation up to 36V
- Ensures high thermal stability across extended industrial temperature ranges
Applications
- Linear regulator circuits
- Adjustable power supply designs
- Switching power supply feedback loops
- Battery charger management systems
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and packaging configuration as defined by Texas Instruments documentation. Confirm that the SOT-23-3 package dimensions match the target PCB footprint requirements. Ensure the selected variant meets the required initial accuracy tolerance for the specific application design constraints.
Selection Notes
Select this component when a low-cost, high-accuracy reference is needed in a compact surface-mount form factor. The 1% initial accuracy suits applications requiring tighter voltage regulation than standard 2% variants. Consider the 100mA sink capability for driving moderate load currents in feedback networks without external buffering.
Part Context
This part belongs to the TL432 family of adjustable precision shunt regulators from Texas Instruments. It serves as a direct alternative to the TL431 series but offers distinct pinout and performance characteristics optimized for low-voltage applications. The 'AQ' designation typically denotes automotive-grade qualification and enhanced reliability standards compared to standard commercial grades.
Replacement Considerations
Direct substitutes include the TL432AQDBZT. Verify pin compatibility and electrical specifications before substitution. Other manufacturers offer equivalent shunt regulators, but functional equivalence requires careful comparison of thermal coefficients and dynamic impedance parameters.
