Overview
The TL432ACDBVR is an adjustable precision shunt regulator manufactured by Texas Instruments, housed in a surface-mount SOT-23-5 package. It features an initial accuracy of 1% and a temperature coefficient of 92 PPM/C. The device supports an output voltage range from approximately 2.5V to 36V, with a maximum input voltage of 36V. It operates within a commercial temperature range of 0°C to +70°C. Key electrical specifications include a maximum shunt current of 100 mA and a minimum cathode current of 600 uA.
Feature Summary
- Provides adjustable reference voltage functionality via external resistors
- Delivers high initial accuracy for precise circuit regulation
- Features low output impedance for stable performance
Applications
- Board-mounted voltage regulators
- Adjustable power supplies
- Switching power supply feedback loops
Procurement Notes
Verify the specific suffix 'DBVR' corresponds to the SOT-23-5 package and reel/cut-tape packaging configuration. Confirm that the AC grade meets the required 1% initial accuracy and 92 PPM/C temperature coefficient for your application. Ensure the operating environment stays within the specified 0°C to +70°C commercial range, as this variant does not support extended industrial or automotive temperatures.
Selection Notes
Select the TL432ACDBVR when a compact SOT-23-5 footprint is required for adjustable shunt regulation in commercial applications. This part is suitable for designs needing 1% accuracy and up to 100mA shunt current. Consider alternative packages like SOT-23-3 if pin count reduction is necessary, or higher temperature grades if operation exceeds 70°C.
Part Context
The TL432 series serves as a three-terminal adjustable shunt regulator, functionally similar to the TL431 but with distinct pinout arrangements for DBV, DBZ, and PK packages. The TL432ACDBVR specifically utilizes the SOT-23-5 package, offering a space-saving solution for precision voltage referencing in portable and consumer electronics compared to traditional through-hole or larger surface-mount alternatives.
FAQ
What is the minimum cathode current required for proper regulation?
The TL432ACDBVR requires a minimum cathode current of 600 uA to maintain regulation.
Does this component support automotive temperature ranges?
No, the TL432ACDBVR is rated for a commercial temperature range of 0°C to +70°C.
