Overview
The TL432LIACDBZR is an adjustable precision shunt regulator manufactured by Texas Instruments, housed in a SOT-23-3 surface-mount package. It operates within a supply voltage range up to 36 V and provides an adjustable output voltage. The device features an initial accuracy of 1% and a temperature coefficient of 63 PPM/C. It supports a maximum shunt current of 15 mA with a minimum operating current of 1 mA. The component functions reliably across a commercial temperature range from 0°C to +70°C.
Feature Summary
- Adjustable output voltage capability via external resistors
- High initial accuracy for precise reference applications
- Low temperature coefficient ensuring thermal stability
Applications
- Board-level voltage regulation
- Adjustable power supply circuits
- Switching power supply feedback loops
Procurement Notes
Verify the specific suffix DBZR corresponds to the SOT-23-3 package configuration. Confirm that the LIAC designation aligns with the required 1% accuracy and 63 PPM/C temperature coefficient specifications. Ensure the commercial temperature range of 0°C to +70°C meets the operational environment requirements before procurement.
Selection Notes
Select this component when a compact three-terminal shunt regulator is needed with tight initial tolerance. The SOT-23-3 package offers space efficiency for dense layouts. Consider the 15 mA current limit for load requirements. Verify that the commercial temperature range suffices for the target application environment.
Part Context
This part belongs to the TL432 family of programmable shunt regulators. It shares functional similarities with the TL431 but utilizes a different pinout compatible with SOT-23 packages. The LIAC variant specifically denotes the accuracy and temperature performance grades within the broader product line.
Replacement Considerations
Direct substitutes include other TL432 variants with matching pinouts and electrical characteristics. Verify package compatibility and ensure equivalent accuracy and temperature ratings are maintained during substitution.
