Overview
The TL432AQDBVTG4 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495 V to 36 V and provides an initial accuracy of 0.5%. The device supports a maximum cathode current of 100 mA with a minimum operating current of 80 µA. It features a temperature coefficient of 34 PPM/°C and functions across an extended industrial temperature range from -40°C to +125°C. The component is housed in a surface-mount SOT-23-5 package.
Feature Summary
- Provides precise adjustable reference voltage regulation
- Ensures high initial accuracy for stable performance
- Supports wide operating temperature ranges
Applications
- Linear regulators
- Adjustable power supplies
- Switching power supplies
- Battery chargers
- Instrumentation circuits
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as documented by Texas Instruments. Confirm the package type matches the required PCB footprint, specifically the SOT-23-5 configuration. Ensure the order quantity aligns with manufacturer reel specifications if bulk procurement is intended. Cross-reference the datasheet revision to confirm electrical characteristics match the design requirements.
Selection Notes
Select this component when high precision and low temperature drift are critical for the application. The 0.5% initial accuracy makes it suitable for sensitive measurement systems. Consider the SOT-23-5 package size constraints during layout planning. Verify that the operating current range meets the circuit's minimum sink requirements to ensure stable regulation under all load conditions.
Part Context
This part belongs to the TL432 family of low-voltage adjustable precision shunt regulators. It serves as a compact alternative to larger three-terminal references. The device integrates a bandgap reference and error amplifier on a single die. It is designed for applications requiring space-saving solutions without compromising regulatory precision or stability.
Replacement Considerations
Direct substitutes include the non-G4 variant TL432AQDBVT. Other compatible options may include TL432AIDBVR or TL432BCDBVRG4, provided pinout and electrical tolerances align with the original design specifications.
