Overview
The TL432ACDBZR is an adjustable precision shunt regulator manufactured by Texas Instruments, housed in a SOT-23-5 surface-mount package. It provides an adjustable output voltage range from 2.5 V to 36 V with an initial accuracy of 1%. The device supports a maximum shunt current of 100 mA and operates within a temperature range of 0°C to +70°C. Key electrical specifications include a maximum series input voltage of 36 V, a minimum shunt current of 600 µA, and a temperature coefficient of 92 PPM/°C.
Feature Summary
- Provides precise adjustable reference voltage functionality for power management circuits
- Features high initial accuracy for stable reference performance
- Supports high shunt current capability for driving loads directly
Applications
- Precision voltage references in portable equipment
- Power supply feedback loops
- Battery-powered systems requiring stable reference voltages
Procurement Notes
Verify the specific suffix 'AC' corresponds to the required 1% initial accuracy and commercial temperature range (0°C to +70°C). Confirm the SOT-23-5 package matches the PCB footprint design. Ensure the maximum shunt current of 100 mA meets the circuit load requirements. Check RoHS compliance status if restricted substances are mandated for the application.
Selection Notes
Select this component when a compact SOT-23-5 package is required alongside 1% accuracy. Compare against TL432LIACDBZR if lower temperature coefficient or different operating temperature ranges are needed. Consider the TL432CDBZR variant if 2.2% accuracy is sufficient for cost reduction. Verify that the 100 mA shunt current capability aligns with the specific circuit design constraints.
Part Context
This part belongs to the TL432 family of adjustable precision shunt regulators from Texas Instruments. These devices serve as low-cost alternatives to Zener diodes, offering superior performance in terms of tolerance and temperature stability. The family includes various packages and accuracy grades to suit diverse industrial and consumer electronics applications.
Replacement Considerations
TL432ACDBZRG4 is a lead-free version of the same device. TL432AQDBZRG4 offers automotive qualification with extended temperature ranges. Direct pin-compatible substitutes may exist from other manufacturers but require verification of electrical parameters.
