Overview
The TL432CDBZR 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 2% and a temperature coefficient of 34 PPM/C. It supports a maximum shunt current of 100 mA with a minimum operating current of 600 uA. The component functions reliably across a commercial temperature range from 0°C to +70°C.
Feature Summary
- Provides adjustable reference voltage functionality suitable for precision regulation applications
- Delivers high thermal stability through low temperature coefficient characteristics
- Offers robust performance with high maximum shunt current capability
Applications
- Board-level voltage regulation circuits
- Adjustable power supply designs
- Switching power supply feedback loops
- Portable equipment power management
Procurement Notes
Verify the specific suffix DBZR corresponds to the SOT-23-3 package configuration. Confirm that the 2% initial accuracy and 34 PPM/C temperature coefficient meet the design requirements. Ensure the commercial temperature range of 0°C to +70°C is sufficient for the intended operating environment. Cross-reference the datasheet for pinout compatibility with existing PCB footprints.
Selection Notes
Select this component when a compact SOT-23-3 form factor is required for space-constrained designs. Choose the TL432CDBZR over higher accuracy variants if the 2% tolerance is acceptable for the application. Consider the 100 mA shunt current limit when designing load conditions. Verify that the commercial temperature range aligns with system thermal constraints compared to automotive or industrial grade alternatives.
Part Context
This part belongs to the TL432 series of adjustable precision shunt regulators from Texas Instruments. It shares functional similarities with the TL431 but utilizes a different pin arrangement compatible with SOT-23 packages. The series is designed to replace Zener diodes in various regulation roles, offering improved stability and adjustability within a small surface-mount footprint.
Replacement Considerations
The TL432CDBZRG4 is a lead-free variant of this component. Other TL432 family members may serve as substitutes if pinout and electrical specifications match, though accuracy and temperature ranges may differ.
